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: 1905 × k = 1900 × k + 5 × k.
  • Each answer is 1905 more than the one before, so you can count on in steps of 1905.

Building it from tables you already know

To multiply 1905 by 9, multiply by 10 and take one 1905 away: 19,050 − 1905 = 17,145. To multiply by 11, multiply by 10 and add one more 1905: 19,050 + 1905 = 20,955. Multiplying by 4 is doubling twice: 1905 → 3,810 → 7,620.

Every multiple of 1905 is at least 1905, so there are none below 100 and 0 below 1,000. A number is in the 1905 times table exactly when it divides by 1905 with no remainder.

Odd, even and the last digit

Because 1905 is odd, the answers alternate between odd and even: 1905 × 1 = 1905 is odd, 1905 × 2 = 3,810 is even, and so on. Multiplying by 10 always puts a zero on the end: 1905 × 10 = 19,050, and 1905 × 100 = 190,500. Multiplying by 5 is half of multiplying by 10: half of 19,050 is 9,525.

Using the 1905 times table to divide

Every fact also works backwards: because 1905 × 7 = 13,335, you know 13,335 ÷ 1905 = 7 and 13,335 ÷ 7 = 1905. Practising the table and its division facts together halves the work.
