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: 1715 × k = 1710 × k + 5 × k.
  • Each answer is 1715 more than the one before, so you can count on in steps of 1715.

Building it from tables you already know

To multiply 1715 by 9, multiply by 10 and take one 1715 away: 17,150 − 1715 = 15,435. To multiply by 11, multiply by 10 and add one more 1715: 17,150 + 1715 = 18,865. Multiplying by 4 is doubling twice: 1715 → 3,430 → 6,860.

Every multiple of 1715 is at least 1715, so there are none below 100 and 0 below 1,000. A number is in the 1715 times table exactly when it divides by 1715 with no remainder.

Odd, even and the last digit

Because 1715 is odd, the answers alternate between odd and even: 1715 × 1 = 1715 is odd, 1715 × 2 = 3,430 is even, and so on. Multiplying by 10 always puts a zero on the end: 1715 × 10 = 17,150, and 1715 × 100 = 171,500. Multiplying by 5 is half of multiplying by 10: half of 17,150 is 8,575.

Using the 1715 times table to divide

Every fact also works backwards: because 1715 × 7 = 12,005, you know 12,005 ÷ 1715 = 7 and 12,005 ÷ 7 = 1715. Practising the table and its division facts together halves the work.
