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: 1903 × k = 1900 × k + 3 × k.
  • Each answer is 1903 more than the one before, so you can count on in steps of 1903.

Building it from tables you already know

To multiply 1903 by 9, multiply by 10 and take one 1903 away: 19,030 − 1903 = 17,127. To multiply by 11, multiply by 10 and add one more 1903: 19,030 + 1903 = 20,933. Multiplying by 4 is doubling twice: 1903 → 3,806 → 7,612.

Every multiple of 1903 is at least 1903, so there are none below 100 and 0 below 1,000. A number is in the 1903 times table exactly when it divides by 1903 with no remainder.

Odd, even and the last digit

Because 1903 is odd, the answers alternate between odd and even: 1903 × 1 = 1903 is odd, 1903 × 2 = 3,806 is even, and so on. Multiplying by 10 always puts a zero on the end: 1903 × 10 = 19,030, and 1903 × 100 = 190,300. Multiplying by 5 is half of multiplying by 10: half of 19,030 is 9,515.

Using the 1903 times table to divide

Every fact also works backwards: because 1903 × 7 = 13,321, you know 13,321 ÷ 1903 = 7 and 13,321 ÷ 7 = 1903. Practising the table and its division facts together halves the work.
