Patterns that help you remember it

  • The last digits repeat in a cycle of 10: 1, 2, 3, 4, 5, 6, 7, 8, 9, 0.
  • Split it into tens and ones: 851 × k = 850 × k + 1 × k.
  • Each answer is 851 more than the one before, so you can count on in steps of 851.

Building it from tables you already know

To multiply 851 by 9, multiply by 10 and take one 851 away: 8,510 − 851 = 7,659. To multiply by 11, multiply by 10 and add one more 851: 8,510 + 851 = 9,361. Multiplying by 4 is doubling twice: 851 → 1,702 → 3,404.

Every multiple of 851 is at least 851, so there are none below 100 and 1 below 1,000. A number is in the 851 times table exactly when it divides by 851 with no remainder.

Odd, even and the last digit

Because 851 is odd, the answers alternate between odd and even: 851 × 1 = 851 is odd, 851 × 2 = 1,702 is even, and so on. Multiplying by 10 always puts a zero on the end: 851 × 10 = 8,510, and 851 × 100 = 85,100. Multiplying by 5 is half of multiplying by 10: half of 8,510 is 4,255.

Using the 851 times table to divide

Every fact also works backwards: because 851 × 7 = 5,957, you know 5,957 ÷ 851 = 7 and 5,957 ÷ 7 = 851. Practising the table and its division facts together halves the work.

Questions

What is 851 × 12?

10,212.

What is half of 851 × 8?

851 × 8 = 6,808, and half of that is 3,404, which is 851 × 4. Halving one factor halves the answer.

What is 851 times 0?

0. Any number multiplied by zero is zero, because zero groups of 851 contain nothing.

What is 851 × 7 and 851 × 8?

851 × 7 = 5,957 and 851 × 8 = 6,808. These two are the facts most people find hardest, so they are worth practising on their own.

Is 12,765 in the 851 times table?

Yes: 12,765 ÷ 851 = 15 with no remainder. 12,766 is not, because dividing it by 851 leaves a remainder of 1.

How do I learn the 851 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.
