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: 1109 × k = 1100 × k + 9 × k.
  • Each answer is 1109 more than the one before, so you can count on in steps of 1109.

Building it from tables you already know

To multiply 1109 by 9, multiply by 10 and take one 1109 away: 11,090 − 1109 = 9,981. To multiply by 11, multiply by 10 and add one more 1109: 11,090 + 1109 = 12,199. Multiplying by 4 is doubling twice: 1109 → 2,218 → 4,436.

Every multiple of 1109 is at least 1109, so there are none below 100 and 0 below 1,000. A number is in the 1109 times table exactly when it divides by 1109 with no remainder.

Odd, even and the last digit

Because 1109 is odd, the answers alternate between odd and even: 1109 × 1 = 1109 is odd, 1109 × 2 = 2,218 is even, and so on. Multiplying by 10 always puts a zero on the end: 1109 × 10 = 11,090, and 1109 × 100 = 110,900. Multiplying by 5 is half of multiplying by 10: half of 11,090 is 5,545.

Using the 1109 times table to divide

Every fact also works backwards: because 1109 × 7 = 7,763, you know 7,763 ÷ 1109 = 7 and 7,763 ÷ 7 = 1109. Practising the table and its division facts together halves the work.
