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: 729 × k = 720 × k + 9 × k.
  • Each answer is 729 more than the one before, so you can count on in steps of 729.

Building it from tables you already know

To multiply 729 by 9, multiply by 10 and take one 729 away: 7,290 − 729 = 6,561. To multiply by 11, multiply by 10 and add one more 729: 7,290 + 729 = 8,019. Multiplying by 4 is doubling twice: 729 → 1,458 → 2,916.

Every multiple of 729 is at least 729, so there are none below 100 and 1 below 1,000. A number is in the 729 times table exactly when it divides by 729 with no remainder.

Odd, even and the last digit

Because 729 is odd, the answers alternate between odd and even: 729 × 1 = 729 is odd, 729 × 2 = 1,458 is even, and so on. Multiplying by 10 always puts a zero on the end: 729 × 10 = 7,290, and 729 × 100 = 72,900. Multiplying by 5 is half of multiplying by 10: half of 7,290 is 3,645.

Using the 729 times table to divide

Every fact also works backwards: because 729 × 7 = 5,103, you know 5,103 ÷ 729 = 7 and 5,103 ÷ 7 = 729. Practising the table and its division facts together halves the work.

Questions

What is 729 × 12?

8,748.

What is half of 729 × 8?

729 × 8 = 5,832, and half of that is 2,916, which is 729 × 4. Halving one factor halves the answer.

What is 729 times 0?
