Patterns that help you remember it

  • The last digits repeat in a cycle of 10: 7, 4, 1, 8, 5, 2, 9, 6, 3, 0.
  • The digits of every answer add up to a multiple of 9.
  • Split it into tens and ones: 1647 × k = 1640 × k + 7 × k.
  • Each answer is 1647 more than the one before, so you can count on in steps of 1647.

Building it from tables you already know

To multiply 1647 by 9, multiply by 10 and take one 1647 away: 16,470 − 1647 = 14,823. To multiply by 11, multiply by 10 and add one more 1647: 16,470 + 1647 = 18,117. Multiplying by 4 is doubling twice: 1647 → 3,294 → 6,588.

Every multiple of 1647 is at least 1647, so there are none below 100 and 0 below 1,000. A number is in the 1647 times table exactly when it divides by 1647 with no remainder.

Odd, even and the last digit

Because 1647 is odd, the answers alternate between odd and even: 1647 × 1 = 1647 is odd, 1647 × 2 = 3,294 is even, and so on. Multiplying by 10 always puts a zero on the end: 1647 × 10 = 16,470, and 1647 × 100 = 164,700. Multiplying by 5 is half of multiplying by 10: half of 16,470 is 8,235.

Using the 1647 times table to divide

Every fact also works backwards: because 1647 × 7 = 11,529, you know 11,529 ÷ 1647 = 7 and 11,529 ÷ 7 = 1647. Practising the table and its division facts together halves the work.
