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: 811 × k = 810 × k + 1 × k.
  • Each answer is 811 more than the one before, so you can count on in steps of 811.

Building it from tables you already know

To multiply 811 by 9, multiply by 10 and take one 811 away: 8,110 − 811 = 7,299. To multiply by 11, multiply by 10 and add one more 811: 8,110 + 811 = 8,921. Multiplying by 4 is doubling twice: 811 → 1,622 → 3,244.

Every multiple of 811 is at least 811, so there are none below 100 and 1 below 1,000. A number is in the 811 times table exactly when it divides by 811 with no remainder.

Odd, even and the last digit

Because 811 is odd, the answers alternate between odd and even: 811 × 1 = 811 is odd, 811 × 2 = 1,622 is even, and so on. Multiplying by 10 always puts a zero on the end: 811 × 10 = 8,110, and 811 × 100 = 81,100. Multiplying by 5 is half of multiplying by 10: half of 8,110 is 4,055.

Using the 811 times table to divide

Every fact also works backwards: because 811 × 7 = 5,677, you know 5,677 ÷ 811 = 7 and 5,677 ÷ 7 = 811. Practising the table and its division facts together halves the work.

Questions

What is 811 × 12?

9,732.

What is half of 811 × 8?

811 × 8 = 6,488, and half of that is 3,244, which is 811 × 4. Halving one factor halves the answer.

What is 811 times 0?

0. Any number multiplied by zero is zero, because zero groups of 811 contain nothing.

What is 811 × 7 and 811 × 8?

811 × 7 = 5,677 and 811 × 8 = 6,488. These two are the facts most people find hardest, so they are worth practising on their own.

Is 12,165 in the 811 times table?

Yes: 12,165 ÷ 811 = 15 with no remainder. 12,166 is not, because dividing it by 811 leaves a remainder of 1.

How do I learn the 811 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.
