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: 1231 × k = 1230 × k + 1 × k.
  • Each answer is 1231 more than the one before, so you can count on in steps of 1231.

Building it from tables you already know

To multiply 1231 by 9, multiply by 10 and take one 1231 away: 12,310 − 1231 = 11,079. To multiply by 11, multiply by 10 and add one more 1231: 12,310 + 1231 = 13,541. Multiplying by 4 is doubling twice: 1231 → 2,462 → 4,924.

Every multiple of 1231 is at least 1231, so there are none below 100 and 0 below 1,000. A number is in the 1231 times table exactly when it divides by 1231 with no remainder.

Odd, even and the last digit

Because 1231 is odd, the answers alternate between odd and even: 1231 × 1 = 1231 is odd, 1231 × 2 = 2,462 is even, and so on. Multiplying by 10 always puts a zero on the end: 1231 × 10 = 12,310, and 1231 × 100 = 123,100. Multiplying by 5 is half of multiplying by 10: half of 12,310 is 6,155.

Using the 1231 times table to divide

Every fact also works backwards: because 1231 × 7 = 8,617, you know 8,617 ÷ 1231 = 7 and 8,617 ÷ 7 = 1231. Practising the table and its division facts together halves the work.
