Patterns that help you remember it

  • The last digits repeat in a cycle of 1: 0.
  • Every answer is even, because 1720 is even.
  • Every answer ends in 0 or 5.
  • Split it into tens and ones: 1720 × k = 1720 × k + 0 × k.
  • Each answer is 1720 more than the one before, so you can count on in steps of 1720.

Building it from tables you already know

Every answer in the 1720 times table is double the answer in the 860 times table: 860 × 6 = 5,160, so 1720 × 6 = 10,320. To multiply 1720 by 9, multiply by 10 and take one 1720 away: 17,200 − 1720 = 15,480. To multiply by 11, multiply by 10 and add one more 1720: 17,200 + 1720 = 18,920. Multiplying by 4 is doubling twice: 1720 → 3,440 → 6,880.

Every multiple of 1720 is at least 1720, so there are none below 100 and 0 below 1,000. A number is in the 1720 times table exactly when it divides by 1720 with no remainder.

Odd, even and the last digit

Because 1720 is even, every answer in its table is even, which is a quick way to catch a wrong answer. Multiplying by 10 always puts a zero on the end: 1720 × 10 = 17,200, and 1720 × 100 = 172,000. Multiplying by 5 is half of multiplying by 10: half of 17,200 is 8,600.

Using the 1720 times table to divide

Every fact also works backwards: because 1720 × 7 = 12,040, you know 12,040 ÷ 1720 = 7 and 12,040 ÷ 7 = 1720. Practising the table and its division facts together halves the work.

Questions

What is 1720 × 12?

20,640.

What is half of 1720 × 8?

1720 × 8 = 13,760, and half of that is 6,880, which is 1720 × 4. Halving one factor halves the answer.

What is 1720 times 0?

0. Any number multiplied by zero is zero, because zero groups of 1720 contain nothing.

What is 1720 × 7 and 1720 × 8?

1720 × 7 = 12,040 and 1720 × 8 = 13,760. These two are the facts most people find hardest, so they are worth practising on their own.

Is 25,800 in the 1720 times table?

Yes: 25,800 ÷ 1720 = 15 with no remainder. 25,801 is not, because dividing it by 1720 leaves a remainder of 1.

How do I learn the 1720 times table quickly?

Learn it in order first, then use the patterns above and practise mixed questions; a few minutes a day works better than one long session.
