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: 991 × k = 990 × k + 1 × k.
  • Each answer is 991 more than the one before, so you can count on in steps of 991.

Building it from tables you already know

To multiply 991 by 9, multiply by 10 and take one 991 away: 9,910 − 991 = 8,919. To multiply by 11, multiply by 10 and add one more 991: 9,910 + 991 = 10,901. Multiplying by 4 is doubling twice: 991 → 1,982 → 3,964.

Every multiple of 991 is at least 991, so there are none below 100 and 1 below 1,000. A number is in the 991 times table exactly when it divides by 991 with no remainder.

Odd, even and the last digit

Because 991 is odd, the answers alternate between odd and even: 991 × 1 = 991 is odd, 991 × 2 = 1,982 is even, and so on. Multiplying by 10 always puts a zero on the end: 991 × 10 = 9,910, and 991 × 100 = 99,100. Multiplying by 5 is half of multiplying by 10: half of 9,910 is 4,955.

Using the 991 times table to divide

Every fact also works backwards: because 991 × 7 = 6,937, you know 6,937 ÷ 991 = 7 and 6,937 ÷ 7 = 991. Practising the table and its division facts together halves the work.

Questions

What is 991 × 12?

11,892.

What is half of 991 × 8?

991 × 8 = 7,928, and half of that is 3,964, which is 991 × 4. Halving one factor halves the answer.

What is 991 times 0?

0. Any number multiplied by zero is zero, because zero groups of 991 contain nothing.

What is 991 × 7 and 991 × 8?

991 × 7 = 6,937 and 991 × 8 = 7,928. These two are the facts most people find hardest, so they are worth practising on their own.

Is 14,865 in the 991 times table?

Yes: 14,865 ÷ 991 = 15 with no remainder. 14,866 is not, because dividing it by 991 leaves a remainder of 1.

How do I learn the 991 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.
