Patterns that help you remember it

  • The last digits repeat in a cycle of 10: 3, 6, 9, 2, 5, 8, 1, 4, 7, 0.
  • Split it into tens and ones: 813 × k = 810 × k + 3 × k.
  • Each answer is 813 more than the one before, so you can count on in steps of 813.

Building it from tables you already know

To multiply 813 by 9, multiply by 10 and take one 813 away: 8,130 − 813 = 7,317. To multiply by 11, multiply by 10 and add one more 813: 8,130 + 813 = 8,943. Multiplying by 4 is doubling twice: 813 → 1,626 → 3,252.

Every multiple of 813 is at least 813, so there are none below 100 and 1 below 1,000. A number is in the 813 times table exactly when it divides by 813 with no remainder.

Odd, even and the last digit

Because 813 is odd, the answers alternate between odd and even: 813 × 1 = 813 is odd, 813 × 2 = 1,626 is even, and so on. Multiplying by 10 always puts a zero on the end: 813 × 10 = 8,130, and 813 × 100 = 81,300. Multiplying by 5 is half of multiplying by 10: half of 8,130 is 4,065.

Using the 813 times table to divide

Every fact also works backwards: because 813 × 7 = 5,691, you know 5,691 ÷ 813 = 7 and 5,691 ÷ 7 = 813. Practising the table and its division facts together halves the work.

Questions

What is 813 × 12?

9,756.

What is half of 813 × 8?

813 × 8 = 6,504, and half of that is 3,252, which is 813 × 4. Halving one factor halves the answer.

What is 813 times 0?

0. Any number multiplied by zero is zero, because zero groups of 813 contain nothing.

What is 813 × 7 and 813 × 8?

813 × 7 = 5,691 and 813 × 8 = 6,504. These two are the facts most people find hardest, so they are worth practising on their own.
