Patterns that help you remember it

  • The last digits repeat in a cycle of 10: 1, 2, 3, 4, 5, 6, 7, 8, 9, 0.
  • Split it into tens and ones: 511 × k = 510 × k + 1 × k.
  • Each answer is 511 more than the one before, so you can count on in steps of 511.

Building it from tables you already know

To multiply 511 by 9, multiply by 10 and take one 511 away: 5,110 − 511 = 4,599. To multiply by 11, multiply by 10 and add one more 511: 5,110 + 511 = 5,621. Multiplying by 4 is doubling twice: 511 → 1,022 → 2,044.

Every multiple of 511 is at least 511, so there are none below 100 and 1 below 1,000. A number is in the 511 times table exactly when it divides by 511 with no remainder.

Odd, even and the last digit

Because 511 is odd, the answers alternate between odd and even: 511 × 1 = 511 is odd, 511 × 2 = 1,022 is even, and so on. Multiplying by 10 always puts a zero on the end: 511 × 10 = 5,110, and 511 × 100 = 51,100. Multiplying by 5 is half of multiplying by 10: half of 5,110 is 2,555.

Using the 511 times table to divide

Every fact also works backwards: because 511 × 7 = 3,577, you know 3,577 ÷ 511 = 7 and 3,577 ÷ 7 = 511. Practising the table and its division facts together halves the work.

Questions

What is 511 × 12?

6,132.

What is half of 511 × 8?

511 × 8 = 4,088, and half of that is 2,044, which is 511 × 4. Halving one factor halves the answer.

What is 511 times 0?

0. Any number multiplied by zero is zero, because zero groups of 511 contain nothing.

What is 511 × 7 and 511 × 8?

511 × 7 = 3,577 and 511 × 8 = 4,088. These two are the facts most people find hardest, so they are worth practising on their own.

Is 7,665 in the 511 times table?

Yes: 7,665 ÷ 511 = 15 with no remainder. 7,666 is not, because dividing it by 511 leaves a remainder of 1.

How do I learn the 511 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.
