Patterns that help you remember it

  • The last digits repeat in a cycle of 10: 9, 8, 7, 6, 5, 4, 3, 2, 1, 0.
  • Split it into tens and ones: 399 × k = 390 × k + 9 × k.
  • Each answer is 399 more than the one before, so you can count on in steps of 399.

Building it from tables you already know

To multiply 399 by 9, multiply by 10 and take one 399 away: 3,990 − 399 = 3,591. To multiply by 11, multiply by 10 and add one more 399: 3,990 + 399 = 4,389. Multiplying by 4 is doubling twice: 399 → 798 → 1,596.

Every multiple of 399 is at least 399, so there are none below 100 and 2 below 1,000. A number is in the 399 times table exactly when it divides by 399 with no remainder.

Odd, even and the last digit

Because 399 is odd, the answers alternate between odd and even: 399 × 1 = 399 is odd, 399 × 2 = 798 is even, and so on. Multiplying by 10 always puts a zero on the end: 399 × 10 = 3,990, and 399 × 100 = 39,900. Multiplying by 5 is half of multiplying by 10: half of 3,990 is 1,995.

Using the 399 times table to divide

Every fact also works backwards: because 399 × 7 = 2,793, you know 2,793 ÷ 399 = 7 and 2,793 ÷ 7 = 399. Practising the table and its division facts together halves the work.
