Patterns that help you remember it

  • The last digits repeat in a cycle of 1: 0.
  • Every answer is even, because 660 is even.
  • Every answer ends in 0 or 5.
  • Split it into tens and ones: 660 × k = 660 × k + 0 × k.
  • Each answer is 660 more than the one before, so you can count on in steps of 660.

Building it from tables you already know

Every answer in the 660 times table is double the answer in the 330 times table: 330 × 6 = 1,980, so 660 × 6 = 3,960. To multiply 660 by 9, multiply by 10 and take one 660 away: 6,600 − 660 = 5,940. To multiply by 11, multiply by 10 and add one more 660: 6,600 + 660 = 7,260. Multiplying by 4 is doubling twice: 660 → 1,320 → 2,640.

Every multiple of 660 is at least 660, so there are none below 100 and 1 below 1,000. A number is in the 660 times table exactly when it divides by 660 with no remainder.

Odd, even and the last digit

Because 660 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: 660 × 10 = 6,600, and 660 × 100 = 66,000. Multiplying by 5 is half of multiplying by 10: half of 6,600 is 3,300.

Using the 660 times table to divide

Every fact also works backwards: because 660 × 7 = 4,620, you know 4,620 ÷ 660 = 7 and 4,620 ÷ 7 = 660. Practising the table and its division facts together halves the work.

Questions

What is 660 × 12?

7,920.

What is half of 660 × 8?

660 × 8 = 5,280, and half of that is 2,640, which is 660 × 4. Halving one factor halves the answer.

What is 660 times 0?

0. Any number multiplied by zero is zero, because zero groups of 660 contain nothing.

What is 660 × 7 and 660 × 8?

660 × 7 = 4,620 and 660 × 8 = 5,280. These two are the facts most people find hardest, so they are worth practising on their own.

Is 9,900 in the 660 times table?

Yes: 9,900 ÷ 660 = 15 with no remainder. 9,901 is not, because dividing it by 660 leaves a remainder of 1.

How do I learn the 660 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.
