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: 1621 × k = 1620 × k + 1 × k.
  • Each answer is 1621 more than the one before, so you can count on in steps of 1621.

Building it from tables you already know

To multiply 1621 by 9, multiply by 10 and take one 1621 away: 16,210 − 1621 = 14,589. To multiply by 11, multiply by 10 and add one more 1621: 16,210 + 1621 = 17,831. Multiplying by 4 is doubling twice: 1621 → 3,242 → 6,484.

Every multiple of 1621 is at least 1621, so there are none below 100 and 0 below 1,000. A number is in the 1621 times table exactly when it divides by 1621 with no remainder.

Odd, even and the last digit

Because 1621 is odd, the answers alternate between odd and even: 1621 × 1 = 1621 is odd, 1621 × 2 = 3,242 is even, and so on. Multiplying by 10 always puts a zero on the end: 1621 × 10 = 16,210, and 1621 × 100 = 162,100. Multiplying by 5 is half of multiplying by 10: half of 16,210 is 8,105.

Using the 1621 times table to divide

Every fact also works backwards: because 1621 × 7 = 11,347, you know 11,347 ÷ 1621 = 7 and 11,347 ÷ 7 = 1621. Practising the table and its division facts together halves the work.
