Patterns that help you remember it

  • The last digits repeat in a cycle of 2: 5, 0.
  • Every answer ends in 0 or 5.
  • Split it into tens and ones: 1685 × k = 1680 × k + 5 × k.
  • Each answer is 1685 more than the one before, so you can count on in steps of 1685.

Building it from tables you already know

To multiply 1685 by 9, multiply by 10 and take one 1685 away: 16,850 − 1685 = 15,165. To multiply by 11, multiply by 10 and add one more 1685: 16,850 + 1685 = 18,535. Multiplying by 4 is doubling twice: 1685 → 3,370 → 6,740.

Every multiple of 1685 is at least 1685, so there are none below 100 and 0 below 1,000. A number is in the 1685 times table exactly when it divides by 1685 with no remainder.

Odd, even and the last digit

Because 1685 is odd, the answers alternate between odd and even: 1685 × 1 = 1685 is odd, 1685 × 2 = 3,370 is even, and so on. Multiplying by 10 always puts a zero on the end: 1685 × 10 = 16,850, and 1685 × 100 = 168,500. Multiplying by 5 is half of multiplying by 10: half of 16,850 is 8,425.

Using the 1685 times table to divide

Every fact also works backwards: because 1685 × 7 = 11,795, you know 11,795 ÷ 1685 = 7 and 11,795 ÷ 7 = 1685. Practising the table and its division facts together halves the work.
