Patterns that help you remember it

  • The last digits repeat in a cycle of 5: 8, 6, 4, 2, 0.
  • Every answer is even, because 128 is even.
  • Split it into tens and ones: 128 × k = 120 × k + 8 × k.
  • Each answer is 128 more than the one before, so you can count on in steps of 128.

Building it from tables you already know

Every answer in the 128 times table is double the answer in the 64 times table: 64 × 6 = 384, so 128 × 6 = 768. To multiply 128 by 9, multiply by 10 and take one 128 away: 1,280 − 128 = 1,152. To multiply by 11, multiply by 10 and add one more 128: 1,280 + 128 = 1,408. Multiplying by 4 is doubling twice: 128 → 256 → 512.

Every multiple of 128 is at least 128, so there are none below 100 and 7 below 1,000. A number is in the 128 times table exactly when it divides by 128 with no remainder.

Odd, even and the last digit

Because 128 is even, every answer in its table is even, which is a quick way to catch a wrong answer. Multiplying by 10 always puts a zero on the end: 128 × 10 = 1,280, and 128 × 100 = 12,800. Multiplying by 5 is half of multiplying by 10: half of 1,280 is 640.

Using the 128 times table to divide

Every fact also works backwards: because 128 × 7 = 896, you know 896 ÷ 128 = 7 and 896 ÷ 7 = 128. Practising the table and its division facts together halves the work.

Questions

What is 128 × 12?

1,536.

What is half of 128 × 8?

128 × 8 = 1,024, and half of that is 512, which is 128 × 4. Halving one factor halves the answer.

What is 128 times 0?

0. Any number multiplied by zero is zero, because zero groups of 128 contain nothing.

What is 128 × 7 and 128 × 8?

128 × 7 = 896 and 128 × 8 = 1,024. These two are the facts most people find hardest, so they are worth practising on their own.

Is 1,920 in the 128 times table?

Yes: 1,920 ÷ 128 = 15 with no remainder. 1,921 is not, because dividing it by 128 leaves a remainder of 1.

How do I learn the 128 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.
