Patterns that help you remember it

  • The last digits repeat in a cycle of 10: 3, 6, 9, 2, 5, 8, 1, 4, 7, 0.
  • Split it into tens and ones: 123 × k = 120 × k + 3 × k.
  • Each answer is 123 more than the one before, so you can count on in steps of 123.

Building it from tables you already know

To multiply 123 by 9, multiply by 10 and take one 123 away: 1,230 − 123 = 1,107. To multiply by 11, multiply by 10 and add one more 123: 1,230 + 123 = 1,353. Multiplying by 4 is doubling twice: 123 → 246 → 492.

Every multiple of 123 is at least 123, so there are none below 100 and 8 below 1,000. A number is in the 123 times table exactly when it divides by 123 with no remainder.

Odd, even and the last digit

Because 123 is odd, the answers alternate between odd and even: 123 × 1 = 123 is odd, 123 × 2 = 246 is even, and so on. Multiplying by 10 always puts a zero on the end: 123 × 10 = 1,230, and 123 × 100 = 12,300. Multiplying by 5 is half of multiplying by 10: half of 1,230 is 615.

Using the 123 times table to divide

Every fact also works backwards: because 123 × 7 = 861, you know 861 ÷ 123 = 7 and 861 ÷ 7 = 123. Practising the table and its division facts together halves the work.

Questions

What is 123 × 12?

1,476.

What is half of 123 × 8?

123 × 8 = 984, and half of that is 492, which is 123 × 4. Halving one factor halves the answer.

What is 123 times 0?

0. Any number multiplied by zero is zero, because zero groups of 123 contain nothing.

What is 123 × 7 and 123 × 8?

123 × 7 = 861 and 123 × 8 = 984. These two are the facts most people find hardest, so they are worth practising on their own.

Is 1,845 in the 123 times table?

Yes: 1,845 ÷ 123 = 15 with no remainder. 1,846 is not, because dividing it by 123 leaves a remainder of 1.

How do I learn the 123 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.
