Patterns that help you remember it

  • The last digits repeat in a cycle of 1: 0.
  • Every answer is even, because 870 is even.
  • Every answer ends in 0 or 5.
  • Split it into tens and ones: 870 × k = 870 × k + 0 × k.
  • Each answer is 870 more than the one before, so you can count on in steps of 870.

Building it from tables you already know

Every answer in the 870 times table is double the answer in the 435 times table: 435 × 6 = 2,610, so 870 × 6 = 5,220. To multiply 870 by 9, multiply by 10 and take one 870 away: 8,700 − 870 = 7,830. To multiply by 11, multiply by 10 and add one more 870: 8,700 + 870 = 9,570. Multiplying by 4 is doubling twice: 870 → 1,740 → 3,480.

Every multiple of 870 is at least 870, so there are none below 100 and 1 below 1,000. A number is in the 870 times table exactly when it divides by 870 with no remainder.

Odd, even and the last digit

Because 870 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: 870 × 10 = 8,700, and 870 × 100 = 87,000. Multiplying by 5 is half of multiplying by 10: half of 8,700 is 4,350.

Using the 870 times table to divide

Every fact also works backwards: because 870 × 7 = 6,090, you know 6,090 ÷ 870 = 7 and 6,090 ÷ 7 = 870. Practising the table and its division facts together halves the work.

Questions

What is 870 × 12?

10,440.

What is half of 870 × 8?

870 × 8 = 6,960, and half of that is 3,480, which is 870 × 4. Halving one factor halves the answer.

What is 870 times 0?

0. Any number multiplied by zero is zero, because zero groups of 870 contain nothing.

What is 870 × 7 and 870 × 8?

870 × 7 = 6,090 and 870 × 8 = 6,960. These two are the facts most people find hardest, so they are worth practising on their own.

Is 13,050 in the 870 times table?

Yes: 13,050 ÷ 870 = 15 with no remainder. 13,051 is not, because dividing it by 870 leaves a remainder of 1.

How do I learn the 870 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.
