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.
  • The digits of every answer add up to a multiple of 9.
  • Split it into tens and ones: 909 × k = 900 × k + 9 × k.
  • Each answer is 909 more than the one before, so you can count on in steps of 909.

Building it from tables you already know

To multiply 909 by 9, multiply by 10 and take one 909 away: 9,090 − 909 = 8,181. To multiply by 11, multiply by 10 and add one more 909: 9,090 + 909 = 9,999. Multiplying by 4 is doubling twice: 909 → 1,818 → 3,636.

Every multiple of 909 is at least 909, so there are none below 100 and 1 below 1,000. A number is in the 909 times table exactly when it divides by 909 with no remainder.

Odd, even and the last digit

Because 909 is odd, the answers alternate between odd and even: 909 × 1 = 909 is odd, 909 × 2 = 1,818 is even, and so on. Multiplying by 10 always puts a zero on the end: 909 × 10 = 9,090, and 909 × 100 = 90,900. Multiplying by 5 is half of multiplying by 10: half of 9,090 is 4,545.

Using the 909 times table to divide

Every fact also works backwards: because 909 × 7 = 6,363, you know 6,363 ÷ 909 = 7 and 6,363 ÷ 7 = 909. Practising the table and its division facts together halves the work.

Questions

What is 909 × 12?

10,908.

What is half of 909 × 8?

909 × 8 = 7,272, and half of that is 3,636, which is 909 × 4. Halving one factor halves the answer.

What is 909 times 0?

0. Any number multiplied by zero is zero, because zero groups of 909 contain nothing.

What is 909 × 7 and 909 × 8?

909 × 7 = 6,363 and 909 × 8 = 7,272. These two are the facts most people find hardest, so they are worth practising on their own.
