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: 1515 × k = 1510 × k + 5 × k.
  • Each answer is 1515 more than the one before, so you can count on in steps of 1515.

Building it from tables you already know

To multiply 1515 by 9, multiply by 10 and take one 1515 away: 15,150 − 1515 = 13,635. To multiply by 11, multiply by 10 and add one more 1515: 15,150 + 1515 = 16,665. Multiplying by 4 is doubling twice: 1515 → 3,030 → 6,060.

Every multiple of 1515 is at least 1515, so there are none below 100 and 0 below 1,000. A number is in the 1515 times table exactly when it divides by 1515 with no remainder.

Odd, even and the last digit

Because 1515 is odd, the answers alternate between odd and even: 1515 × 1 = 1515 is odd, 1515 × 2 = 3,030 is even, and so on. Multiplying by 10 always puts a zero on the end: 1515 × 10 = 15,150, and 1515 × 100 = 151,500. Multiplying by 5 is half of multiplying by 10: half of 15,150 is 7,575.

Using the 1515 times table to divide

Every fact also works backwards: because 1515 × 7 = 10,605, you know 10,605 ÷ 1515 = 7 and 10,605 ÷ 7 = 1515. Practising the table and its division facts together halves the work.
