Patterns that help you remember it

  • The last digits repeat in a cycle of 2: 5, 0.
  • Every answer ends in 0 or 5.
  • Split it into tens and ones: 845 × k = 840 × k + 5 × k.
  • Each answer is 845 more than the one before, so you can count on in steps of 845.

Building it from tables you already know

To multiply 845 by 9, multiply by 10 and take one 845 away: 8,450 − 845 = 7,605. To multiply by 11, multiply by 10 and add one more 845: 8,450 + 845 = 9,295. Multiplying by 4 is doubling twice: 845 → 1,690 → 3,380.

Every multiple of 845 is at least 845, so there are none below 100 and 1 below 1,000. A number is in the 845 times table exactly when it divides by 845 with no remainder.

Odd, even and the last digit

Because 845 is odd, the answers alternate between odd and even: 845 × 1 = 845 is odd, 845 × 2 = 1,690 is even, and so on. Multiplying by 10 always puts a zero on the end: 845 × 10 = 8,450, and 845 × 100 = 84,500. Multiplying by 5 is half of multiplying by 10: half of 8,450 is 4,225.

Using the 845 times table to divide

Every fact also works backwards: because 845 × 7 = 5,915, you know 5,915 ÷ 845 = 7 and 5,915 ÷ 7 = 845. Practising the table and its division facts together halves the work.
