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: 1615 × k = 1610 × k + 5 × k.
  • Each answer is 1615 more than the one before, so you can count on in steps of 1615.

Building it from tables you already know

To multiply 1615 by 9, multiply by 10 and take one 1615 away: 16,150 − 1615 = 14,535. To multiply by 11, multiply by 10 and add one more 1615: 16,150 + 1615 = 17,765. Multiplying by 4 is doubling twice: 1615 → 3,230 → 6,460.

Every multiple of 1615 is at least 1615, so there are none below 100 and 0 below 1,000. A number is in the 1615 times table exactly when it divides by 1615 with no remainder.

Odd, even and the last digit

Because 1615 is odd, the answers alternate between odd and even: 1615 × 1 = 1615 is odd, 1615 × 2 = 3,230 is even, and so on. Multiplying by 10 always puts a zero on the end: 1615 × 10 = 16,150, and 1615 × 100 = 161,500. Multiplying by 5 is half of multiplying by 10: half of 16,150 is 8,075.

Using the 1615 times table to divide

Every fact also works backwards: because 1615 × 7 = 11,305, you know 11,305 ÷ 1615 = 7 and 11,305 ÷ 7 = 1615. Practising the table and its division facts together halves the work.
