Patterns that help you remember it

  • The last digits repeat in a cycle of 10: 1, 2, 3, 4, 5, 6, 7, 8, 9, 0.
  • Split it into tens and ones: 1851 × k = 1850 × k + 1 × k.
  • Each answer is 1851 more than the one before, so you can count on in steps of 1851.

Building it from tables you already know

To multiply 1851 by 9, multiply by 10 and take one 1851 away: 18,510 − 1851 = 16,659. To multiply by 11, multiply by 10 and add one more 1851: 18,510 + 1851 = 20,361. Multiplying by 4 is doubling twice: 1851 → 3,702 → 7,404.

Every multiple of 1851 is at least 1851, so there are none below 100 and 0 below 1,000. A number is in the 1851 times table exactly when it divides by 1851 with no remainder.

Odd, even and the last digit

Because 1851 is odd, the answers alternate between odd and even: 1851 × 1 = 1851 is odd, 1851 × 2 = 3,702 is even, and so on. Multiplying by 10 always puts a zero on the end: 1851 × 10 = 18,510, and 1851 × 100 = 185,100. Multiplying by 5 is half of multiplying by 10: half of 18,510 is 9,255.

Using the 1851 times table to divide

Every fact also works backwards: because 1851 × 7 = 12,957, you know 12,957 ÷ 1851 = 7 and 12,957 ÷ 7 = 1851. Practising the table and its division facts together halves the work.
