Patterns that help you remember it

  • The last digits repeat in a cycle of 2: 5, 0.
  • The digits of every answer add up to a multiple of 9.
  • Every answer ends in 0 or 5.
  • Split it into tens and ones: 1845 × k = 1840 × k + 5 × k.
  • Each answer is 1845 more than the one before, so you can count on in steps of 1845.

Building it from tables you already know

To multiply 1845 by 9, multiply by 10 and take one 1845 away: 18,450 − 1845 = 16,605. To multiply by 11, multiply by 10 and add one more 1845: 18,450 + 1845 = 20,295. Multiplying by 4 is doubling twice: 1845 → 3,690 → 7,380.

Every multiple of 1845 is at least 1845, so there are none below 100 and 0 below 1,000. A number is in the 1845 times table exactly when it divides by 1845 with no remainder.

Odd, even and the last digit

Because 1845 is odd, the answers alternate between odd and even: 1845 × 1 = 1845 is odd, 1845 × 2 = 3,690 is even, and so on. Multiplying by 10 always puts a zero on the end: 1845 × 10 = 18,450, and 1845 × 100 = 184,500. Multiplying by 5 is half of multiplying by 10: half of 18,450 is 9,225.

Using the 1845 times table to divide

Every fact also works backwards: because 1845 × 7 = 12,915, you know 12,915 ÷ 1845 = 7 and 12,915 ÷ 7 = 1845. Practising the table and its division facts together halves the work.
