Patterns that help you remember it

  • The last digits repeat in a cycle of 10: 9, 8, 7, 6, 5, 4, 3, 2, 1, 0.
  • Split it into tens and ones: 309 × k = 300 × k + 9 × k.
  • Each answer is 309 more than the one before, so you can count on in steps of 309.

Building it from tables you already know

To multiply 309 by 9, multiply by 10 and take one 309 away: 3,090 − 309 = 2,781. To multiply by 11, multiply by 10 and add one more 309: 3,090 + 309 = 3,399. Multiplying by 4 is doubling twice: 309 → 618 → 1,236.

Every multiple of 309 is at least 309, so there are none below 100 and 3 below 1,000. A number is in the 309 times table exactly when it divides by 309 with no remainder.

Odd, even and the last digit

Because 309 is odd, the answers alternate between odd and even: 309 × 1 = 309 is odd, 309 × 2 = 618 is even, and so on. Multiplying by 10 always puts a zero on the end: 309 × 10 = 3,090, and 309 × 100 = 30,900. Multiplying by 5 is half of multiplying by 10: half of 3,090 is 1,545.

Using the 309 times table to divide

Every fact also works backwards: because 309 × 7 = 2,163, you know 2,163 ÷ 309 = 7 and 2,163 ÷ 7 = 309. Practising the table and its division facts together halves the work.

Questions

What is 309 × 12?

3,708.

What is half of 309 × 8?

309 × 8 = 2,472, and half of that is 1,236, which is 309 × 4. Halving one factor halves the answer.

What is 309 times 0?

0. Any number multiplied by zero is zero, because zero groups of 309 contain nothing.

What is 309 × 7 and 309 × 8?

309 × 7 = 2,163 and 309 × 8 = 2,472. These two are the facts most people find hardest, so they are worth practising on their own.

Is 4,635 in the 309 times table?

Yes: 4,635 ÷ 309 = 15 with no remainder. 4,636 is not, because dividing it by 309 leaves a remainder of 1.

How do I learn the 309 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.
