Patterns that help you remember it

  • The last digits repeat in a cycle of 5: 4, 8, 2, 6, 0.
  • Every answer is even, because 664 is even.
  • Split it into tens and ones: 664 × k = 660 × k + 4 × k.
  • Each answer is 664 more than the one before, so you can count on in steps of 664.

Building it from tables you already know

Every answer in the 664 times table is double the answer in the 332 times table: 332 × 6 = 1,992, so 664 × 6 = 3,984. To multiply 664 by 9, multiply by 10 and take one 664 away: 6,640 − 664 = 5,976. To multiply by 11, multiply by 10 and add one more 664: 6,640 + 664 = 7,304. Multiplying by 4 is doubling twice: 664 → 1,328 → 2,656.

Every multiple of 664 is at least 664, so there are none below 100 and 1 below 1,000. A number is in the 664 times table exactly when it divides by 664 with no remainder.

Odd, even and the last digit

Because 664 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: 664 × 10 = 6,640, and 664 × 100 = 66,400. Multiplying by 5 is half of multiplying by 10: half of 6,640 is 3,320.

Using the 664 times table to divide

Every fact also works backwards: because 664 × 7 = 4,648, you know 4,648 ÷ 664 = 7 and 4,648 ÷ 7 = 664. Practising the table and its division facts together halves the work.

Questions

What is 664 × 12?

7,968.

What is half of 664 × 8?

664 × 8 = 5,312, and half of that is 2,656, which is 664 × 4. Halving one factor halves the answer.

What is 664 times 0?
