Patterns that help you remember it

  • The last digits repeat in a cycle of 5: 6, 2, 8, 4, 0.
  • Every answer is even, because 686 is even.
  • Split it into tens and ones: 686 × k = 680 × k + 6 × k.
  • Each answer is 686 more than the one before, so you can count on in steps of 686.

Building it from tables you already know

Every answer in the 686 times table is double the answer in the 343 times table: 343 × 6 = 2,058, so 686 × 6 = 4,116. To multiply 686 by 9, multiply by 10 and take one 686 away: 6,860 − 686 = 6,174. To multiply by 11, multiply by 10 and add one more 686: 6,860 + 686 = 7,546. Multiplying by 4 is doubling twice: 686 → 1,372 → 2,744.

Every multiple of 686 is at least 686, so there are none below 100 and 1 below 1,000. A number is in the 686 times table exactly when it divides by 686 with no remainder.

Odd, even and the last digit

Because 686 is even, every answer in its table is even, which is a quick way to catch a wrong answer. Multiplying by 10 always puts a zero on the end: 686 × 10 = 6,860, and 686 × 100 = 68,600. Multiplying by 5 is half of multiplying by 10: half of 6,860 is 3,430.

Using the 686 times table to divide

Every fact also works backwards: because 686 × 7 = 4,802, you know 4,802 ÷ 686 = 7 and 4,802 ÷ 7 = 686. Practising the table and its division facts together halves the work.
