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: 285 × k = 280 × k + 5 × k.
  • Each answer is 285 more than the one before, so you can count on in steps of 285.

Building it from tables you already know

To multiply 285 by 9, multiply by 10 and take one 285 away: 2,850 − 285 = 2,565. To multiply by 11, multiply by 10 and add one more 285: 2,850 + 285 = 3,135. Multiplying by 4 is doubling twice: 285 → 570 → 1,140.

Every multiple of 285 is at least 285, so there are none below 100 and 3 below 1,000. A number is in the 285 times table exactly when it divides by 285 with no remainder.

Odd, even and the last digit

Because 285 is odd, the answers alternate between odd and even: 285 × 1 = 285 is odd, 285 × 2 = 570 is even, and so on. Multiplying by 10 always puts a zero on the end: 285 × 10 = 2,850, and 285 × 100 = 28,500. Multiplying by 5 is half of multiplying by 10: half of 2,850 is 1,425.

Using the 285 times table to divide

Every fact also works backwards: because 285 × 7 = 1,995, you know 1,995 ÷ 285 = 7 and 1,995 ÷ 7 = 285. Practising the table and its division facts together halves the work.

Questions

What is 285 × 12?

3,420.

What is half of 285 × 8?

285 × 8 = 2,280, and half of that is 1,140, which is 285 × 4. Halving one factor halves the answer.

What is 285 times 0?

0. Any number multiplied by zero is zero, because zero groups of 285 contain nothing.

What is 285 × 7 and 285 × 8?

285 × 7 = 1,995 and 285 × 8 = 2,280. These two are the facts most people find hardest, so they are worth practising on their own.

Is 4,275 in the 285 times table?

Yes: 4,275 ÷ 285 = 15 with no remainder. 4,276 is not, because dividing it by 285 leaves a remainder of 1.

How do I learn the 285 times table quickly?

Learn it in order first, then use the patterns above and practise mixed questions; a few minutes a day works better than one long session.
