Patterns that help you remember it

  • The last digits repeat in a cycle of 10: 1, 2, 3, 4, 5, 6, 7, 8, 9, 0.
  • Split it into tens and ones: 721 × k = 720 × k + 1 × k.
  • Each answer is 721 more than the one before, so you can count on in steps of 721.

Building it from tables you already know

To multiply 721 by 9, multiply by 10 and take one 721 away: 7,210 − 721 = 6,489. To multiply by 11, multiply by 10 and add one more 721: 7,210 + 721 = 7,931. Multiplying by 4 is doubling twice: 721 → 1,442 → 2,884.

Every multiple of 721 is at least 721, so there are none below 100 and 1 below 1,000. A number is in the 721 times table exactly when it divides by 721 with no remainder.

Odd, even and the last digit

Because 721 is odd, the answers alternate between odd and even: 721 × 1 = 721 is odd, 721 × 2 = 1,442 is even, and so on. Multiplying by 10 always puts a zero on the end: 721 × 10 = 7,210, and 721 × 100 = 72,100. Multiplying by 5 is half of multiplying by 10: half of 7,210 is 3,605.

Using the 721 times table to divide

Every fact also works backwards: because 721 × 7 = 5,047, you know 5,047 ÷ 721 = 7 and 5,047 ÷ 7 = 721. Practising the table and its division facts together halves the work.

Questions

What is 721 × 12?

8,652.

What is half of 721 × 8?

721 × 8 = 5,768, and half of that is 2,884, which is 721 × 4. Halving one factor halves the answer.

What is 721 times 0?

0. Any number multiplied by zero is zero, because zero groups of 721 contain nothing.

What is 721 × 7 and 721 × 8?

721 × 7 = 5,047 and 721 × 8 = 5,768. These two are the facts most people find hardest, so they are worth practising on their own.

Is 10,815 in the 721 times table?

Yes: 10,815 ÷ 721 = 15 with no remainder. 10,816 is not, because dividing it by 721 leaves a remainder of 1.

How do I learn the 721 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.
