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: 831 × k = 830 × k + 1 × k.
  • Each answer is 831 more than the one before, so you can count on in steps of 831.

Building it from tables you already know

To multiply 831 by 9, multiply by 10 and take one 831 away: 8,310 − 831 = 7,479. To multiply by 11, multiply by 10 and add one more 831: 8,310 + 831 = 9,141. Multiplying by 4 is doubling twice: 831 → 1,662 → 3,324.

Every multiple of 831 is at least 831, so there are none below 100 and 1 below 1,000. A number is in the 831 times table exactly when it divides by 831 with no remainder.

Odd, even and the last digit

Because 831 is odd, the answers alternate between odd and even: 831 × 1 = 831 is odd, 831 × 2 = 1,662 is even, and so on. Multiplying by 10 always puts a zero on the end: 831 × 10 = 8,310, and 831 × 100 = 83,100. Multiplying by 5 is half of multiplying by 10: half of 8,310 is 4,155.

Using the 831 times table to divide

Every fact also works backwards: because 831 × 7 = 5,817, you know 5,817 ÷ 831 = 7 and 5,817 ÷ 7 = 831. Practising the table and its division facts together halves the work.

Questions

What is 831 × 12?

9,972.

What is half of 831 × 8?

831 × 8 = 6,648, and half of that is 3,324, which is 831 × 4. Halving one factor halves the answer.

What is 831 times 0?

0. Any number multiplied by zero is zero, because zero groups of 831 contain nothing.

What is 831 × 7 and 831 × 8?

831 × 7 = 5,817 and 831 × 8 = 6,648. These two are the facts most people find hardest, so they are worth practising on their own.

Is 12,465 in the 831 times table?

Yes: 12,465 ÷ 831 = 15 with no remainder. 12,466 is not, because dividing it by 831 leaves a remainder of 1.

How do I learn the 831 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.
