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: 685 × k = 680 × k + 5 × k.
  • Each answer is 685 more than the one before, so you can count on in steps of 685.

Building it from tables you already know

To multiply 685 by 9, multiply by 10 and take one 685 away: 6,850 − 685 = 6,165. To multiply by 11, multiply by 10 and add one more 685: 6,850 + 685 = 7,535. Multiplying by 4 is doubling twice: 685 → 1,370 → 2,740.

Every multiple of 685 is at least 685, so there are none below 100 and 1 below 1,000. A number is in the 685 times table exactly when it divides by 685 with no remainder.

Odd, even and the last digit

Because 685 is odd, the answers alternate between odd and even: 685 × 1 = 685 is odd, 685 × 2 = 1,370 is even, and so on. Multiplying by 10 always puts a zero on the end: 685 × 10 = 6,850, and 685 × 100 = 68,500. Multiplying by 5 is half of multiplying by 10: half of 6,850 is 3,425.

Using the 685 times table to divide

Every fact also works backwards: because 685 × 7 = 4,795, you know 4,795 ÷ 685 = 7 and 4,795 ÷ 7 = 685. Practising the table and its division facts together halves the work.

Questions

What is 685 × 12?

8,220.

What is half of 685 × 8?

685 × 8 = 5,480, and half of that is 2,740, which is 685 × 4. Halving one factor halves the answer.

What is 685 times 0?

0. Any number multiplied by zero is zero, because zero groups of 685 contain nothing.

What is 685 × 7 and 685 × 8?

685 × 7 = 4,795 and 685 × 8 = 5,480. These two are the facts most people find hardest, so they are worth practising on their own.
