Read the full guide
What a 500 multiplication chart holds
The chart has 250,000 squares but only 64,673 different answers. The most common are 5040 and 10,080, the minutes in a week: each sits in 40 squares. Another 266 answers appear just once, among them 499 × 499 = 249,001. The list All 45 facts, further down, picks out 45 of them.
Moving and printing
Type 480 and 21 into Find and press Go: the chart moves to rows 461 to 480 and picks out 480 × 21 = 10,080. Each arrow button names the rows or columns it leads to. Print this part gives the block in view on one page. Print 25 pages gives the 100 rows by 100 columns that hold the block you are on.
Row 500 needs no chart: halve the column number and call it thousands, so 500 × 7 = 3500.
Questions and answers
Does a multiplication chart up to 500 mean rows or answers?
Here it means rows and columns numbered 1 to 500, so answers run to 250,000. Every answer of 500 or less sits in the first 22 rows or the first 22 columns, 3,190 squares in all. The 1-24 chart ends nearest, at 576.
How do I print the 1-500 chart?
Press Print this part for the 20 by 20 block in view: one page, Letter or A4, with a name and date line. Print 25 pages gives the blocks around it. With Blank or Partly blank chosen, the single block gets an answer key.
Can I save the chart as a PDF?
Yes, through the print window. Press Print this part or Print 25 pages, then pick Save as PDF as the printer. There is no ready-made file, because the whole chart would run to 625 pages.
Where is the 500 times table on the 1-500 chart?
In row 500 and in column 500, from 500 × 1 = 500 to 500 × 500 = 250,000. Type 500 and 1 into Find to reach its first 20 answers.
All 45 facts
Corners and last rows 6
301 × 4 = 1204Row 301 is the first row the 1-300 chart does not have. 300 × 4 = 1200, and one more 4 makes 1204.
498 × 4 = 1992498 is 2 short of 500, and there are 4 of them. Start from 500 × 4 = 2000 and take off 4 twos, which is 8.
500 × 1 = 500The answer 500 sits in only 12 squares: 1 × 500, 2 × 250, 4 × 125, 5 × 100, 10 × 50, 20 × 25 and their turnarounds. Compare 360, which sits in 24.
500 × 7 = 3500Row 500 has a shortcut: halve the column number and call it thousands. Half of 7 is 3 and a half, so the answer is 3 and a half thousands.
500 × 250 = 125,000The row 500 shortcut again: half of 250 is 125, so the answer is 125 thousands. That is one eighth of a million.
500 × 500 = 250,000The last square of the chart, bottom right. A picture 500 pixels wide and 500 tall has 250,000 pixels, a quarter of a megapixel.

Squares on the diagonal 8
307 × 307 = 94,249This answer reads the same forward and backward. From row 301 to row 500 no other square number on the diagonal does.
316 × 316 = 99,856The last square number with 5 digits. One step down the diagonal, 317 × 317 = 100,489 has 6.
324 × 324 = 104,976324 is 18 × 18, so this answer is 18 × 18 × 18 × 18.
343 × 343 = 117,649343 is 7 × 7 × 7, so this square number is six 7s multiplied together.
365 × 365 = 133,225The days in a common year, squared. 365 is also 10 × 10 + 11 × 11 + 12 × 12, and it is 13 × 13 + 14 × 14 too.
376 × 376 = 141,376Look at the last three digits of the answer: 376 again. It is the only number from 301 to 500 whose square ends in itself.
450 × 450 = 202,50045 × 45 = 2025, and 20 + 25 = 45. Each 450 brings one extra zero, so 2025 becomes 202,500.
499 × 499 = 249,001499 is the largest prime number on the chart, so nothing else on the chart multiplies to 249,001. The answer sits in exactly 1 square.
Round answers 6
320 × 125 = 40,0008 × 125 = 1000 and 32 is four 8s, so 32 × 125 = 4000. The 0 of 320 makes it 40,000.
350 × 20 = 700035 × 2 = 70, then two zeros, one from 350 and one from 20.
375 × 8 = 3000Eight 375s make exactly 3000. 375 is 3 lots of 125, and eight 125s make 1000.
425 × 4 = 1700Split 425 into 400 and 25. 400 × 4 = 1600 and 25 × 4 = 100, which add to 1700.
444 × 25 = 11,100444 is 111 fours, and every 4 × 25 makes 100, so the answer is 111 hundreds.
500 × 200 = 100,000The first answer in row 500 with 6 digits. One column to the left, 500 × 199 = 99,500 still has 5.
Number patterns 6
333 × 3 = 999The largest 3-digit answer in column 3. 333 is 3 × 111, so the answer is 9 × 111.
371 × 370 = 137,270Two neighbors with a rare trick. Cube each digit of 370 and add: 27 + 343 + 0 = 370. Do the same for 371 and the extra 1 gives 371.
385 × 13 = 5005385 is 5 × 7 × 11, and 7 × 11 × 13 = 1001. So 13 of them make 5 × 1001, a 5 at each end with zeros between.
404 × 396 = 159,984Two numbers the same distance from 400, one 4 above and one 4 below. Their answer is 400 × 400 less 4 × 4, which is 160,000 − 16.
407 × 273 = 111,111Six 1s again from a different pair: 407 is 11 × 37 and 273 is 3 × 7 × 13. 407 is also 4 × 4 × 4 + 0 + 7 × 7 × 7, the cubes of its own digits added up.
481 × 231 = 111,111Six 1s in a row. 481 is 13 × 37 and 231 is 3 × 7 × 11. The answer 111,111 sits in 6 squares of this chart and in none on the 1-300 chart.
Common and rare answers 5
360 × 1 = 360The answer 360 sits in 24 squares, one for each number that divides it. Of all the answers up to 500, only 420 and 480 sit in as many.
420 × 12 = 50405040 is 1 × 2 × 3 × 4 × 5 × 6 × 7, the number of ways 7 children can stand in a line. It shares first place as the most common answer on the chart: 40 squares.
480 × 21 = 10,080The minutes in a week: 7 days of 24 hours of 60 minutes. It ties with 5040 as the most common answer, 40 squares each. No other answer sits in more than 38.
487 × 487 = 237,169One of 266 answers that sit in exactly 1 square of the chart. Every answer that appears an odd number of times is a square number, because every other spot on the chart pairs up with its turnaround.
499 × 491 = 245,009Two primes, the largest pair on the chart. Nothing else divides 245,009, so it appears only here and at the turnaround, 491 × 499.
Time, sound, paper and screens 14
320 × 240 = 76,800A 320 by 240 screen, called QVGA, shows 76,800 pixels. That is a quarter of the 307,200 pixels of a 640 by 480 VGA screen.
343 × 3 = 1029Sound moves through air at about 343 meters a second when the air is 20 °C. In 3 seconds it covers 1029 meters, a little more than a kilometer.
360 × 60 = 21,600A full turn is 360 degrees, and each degree splits into 60 arcminutes, so a full turn is 21,600 arcminutes.
365 × 24 = 8760A common year has 365 days of 24 hours each, so it lasts 8760 hours.
366 × 24 = 8784A leap year has one extra day, so it lasts 24 hours longer than a common year: 8784 hours.
400 × 25 = 10,000One lap of a running track is 400 meters, so the 10,000 meter race is 25 laps.
400 × 365 = 146,000The calendar repeats every 400 years. 400 years of 365 days is 146,000 days. The 97 leap days in that stretch bring it to 146,097 days, which is exactly 20,871 weeks.
420 × 297 = 124,740A sheet of A3 paper is 297 mm by 420 mm, so it covers 124,740 square millimeters. That is two A4 sheets side by side.
440 × 2 = 880The standard tuning note, the A above middle C, is 440 hertz, which means 440 vibrations a second. The A one octave higher vibrates twice as fast, at 880 hertz.
440 × 4 = 1760A mile is 1760 yards, so a quarter mile is 440 yards.
480 × 60 = 28,8008 hours is 480 minutes, and each minute is 60 seconds, so 8 hours lasts 28,800 seconds.
480 × 320 = 153,600A 480 by 320 screen, one of the sizes called HVGA, shows 153,600 pixels, half of what a 640 by 480 VGA screen shows.
500 × 4 = 2000A half liter bottle holds 500 milliliters. Four of them hold 2000 milliliters, which is 2 liters.
500 × 10 = 5000A ream of paper is 500 sheets, so 10 reams hold 5000 sheets.
