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 1664 is even.
  • Split it into tens and ones: 1664 × k = 1660 × k + 4 × k.
  • Each answer is 1664 more than the one before, so you can count on in steps of 1664.

Building it from tables you already know

Every answer in the 1664 times table is double the answer in the 832 times table: 832 × 6 = 4,992, so 1664 × 6 = 9,984. To multiply 1664 by 9, multiply by 10 and take one 1664 away: 16,640 − 1664 = 14,976. To multiply by 11, multiply by 10 and add one more 1664: 16,640 + 1664 = 18,304. Multiplying by 4 is doubling twice: 1664 → 3,328 → 6,656.

Every multiple of 1664 is at least 1664, so there are none below 100 and 0 below 1,000. A number is in the 1664 times table exactly when it divides by 1664 with no remainder.

Odd, even and the last digit

Because 1664 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: 1664 × 10 = 16,640, and 1664 × 100 = 166,400. Multiplying by 5 is half of multiplying by 10: half of 16,640 is 8,320.

Using the 1664 times table to divide

Every fact also works backwards: because 1664 × 7 = 11,648, you know 11,648 ÷ 1664 = 7 and 11,648 ÷ 7 = 1664. Practising the table and its division facts together halves the work.
