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: 1631 × k = 1630 × k + 1 × k.
  • Each answer is 1631 more than the one before, so you can count on in steps of 1631.

Building it from tables you already know

To multiply 1631 by 9, multiply by 10 and take one 1631 away: 16,310 − 1631 = 14,679. To multiply by 11, multiply by 10 and add one more 1631: 16,310 + 1631 = 17,941. Multiplying by 4 is doubling twice: 1631 → 3,262 → 6,524.

Every multiple of 1631 is at least 1631, so there are none below 100 and 0 below 1,000. A number is in the 1631 times table exactly when it divides by 1631 with no remainder.

Odd, even and the last digit

Because 1631 is odd, the answers alternate between odd and even: 1631 × 1 = 1631 is odd, 1631 × 2 = 3,262 is even, and so on. Multiplying by 10 always puts a zero on the end: 1631 × 10 = 16,310, and 1631 × 100 = 163,100. Multiplying by 5 is half of multiplying by 10: half of 16,310 is 8,155.

Using the 1631 times table to divide

Every fact also works backwards: because 1631 × 7 = 11,417, you know 11,417 ÷ 1631 = 7 and 11,417 ÷ 7 = 1631. Practising the table and its division facts together halves the work.
