Patterns that help you remember it

  • The last digits repeat in a cycle of 1: 0.
  • Every answer is even, because 680 is even.
  • Every answer ends in 0 or 5.
  • Split it into tens and ones: 680 × k = 680 × k + 0 × k.
  • Each answer is 680 more than the one before, so you can count on in steps of 680.

Building it from tables you already know

Every answer in the 680 times table is double the answer in the 340 times table: 340 × 6 = 2,040, so 680 × 6 = 4,080. To multiply 680 by 9, multiply by 10 and take one 680 away: 6,800 − 680 = 6,120. To multiply by 11, multiply by 10 and add one more 680: 6,800 + 680 = 7,480. Multiplying by 4 is doubling twice: 680 → 1,360 → 2,720.

Every multiple of 680 is at least 680, so there are none below 100 and 1 below 1,000. A number is in the 680 times table exactly when it divides by 680 with no remainder.

Odd, even and the last digit

Because 680 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: 680 × 10 = 6,800, and 680 × 100 = 68,000. Multiplying by 5 is half of multiplying by 10: half of 6,800 is 3,400.

Using the 680 times table to divide

Every fact also works backwards: because 680 × 7 = 4,760, you know 4,760 ÷ 680 = 7 and 4,760 ÷ 7 = 680. Practising the table and its division facts together halves the work.

Word problems

Times tables are most useful when you can spot them in a question. Try these, then open each one to check:

Questions

What is 680 × 12?

8,160.

What is half of 680 × 8?

680 × 8 = 5,440, and half of that is 2,720, which is 680 × 4. Halving one factor halves the answer.

What is 680 times 0?

0. Any number multiplied by zero is zero, because zero groups of 680 contain nothing.

What is 680 × 7 and 680 × 8?

680 × 7 = 4,760 and 680 × 8 = 5,440. These two are the facts most people find hardest, so they are worth practising on their own.

Is 10,200 in the 680 times table?

Yes: 10,200 ÷ 680 = 15 with no remainder. 10,201 is not, because dividing it by 680 leaves a remainder of 1.

How do I learn the 680 times table quickly?

Learn it in order first, then use the patterns above and practise mixed questions; a few minutes a day works better than one long session.
