Patterns that help you remember it

  • The last digits repeat in a cycle of 1: 0.
  • Every answer is even, because 810 is even.
  • The digits of every answer add up to a multiple of 9.
  • Every answer ends in 0 or 5.
  • Split it into tens and ones: 810 × k = 810 × k + 0 × k.
  • Each answer is 810 more than the one before, so you can count on in steps of 810.

Building it from tables you already know

Every answer in the 810 times table is double the answer in the 405 times table: 405 × 6 = 2,430, so 810 × 6 = 4,860. To multiply 810 by 9, multiply by 10 and take one 810 away: 8,100 − 810 = 7,290. To multiply by 11, multiply by 10 and add one more 810: 8,100 + 810 = 8,910. Multiplying by 4 is doubling twice: 810 → 1,620 → 3,240.

Every multiple of 810 is at least 810, so there are none below 100 and 1 below 1,000. A number is in the 810 times table exactly when it divides by 810 with no remainder.

Odd, even and the last digit

Because 810 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: 810 × 10 = 8,100, and 810 × 100 = 81,000. Multiplying by 5 is half of multiplying by 10: half of 8,100 is 4,050.

Using the 810 times table to divide

Every fact also works backwards: because 810 × 7 = 5,670, you know 5,670 ÷ 810 = 7 and 5,670 ÷ 7 = 810. 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:

  1. A box holds 810 pencils. How many pencils are in 5 boxes?
    Answer5 × 810 = 4,050 pencils.
  2. Tickets cost $810 each. How much do 4 tickets cost?
    Answer4 × $810 = $3,240.
  3. 4,860 chairs are set out in rows of 810. How many rows are there?
    Answer4,860 ÷ 810 = 6 rows.
  4. A plant grows 810 millimetres a week. How much does it grow in 8 weeks?

Questions

What is 810 × 12?

9,720.

What is half of 810 × 8?

810 × 8 = 6,480, and half of that is 3,240, which is 810 × 4. Halving one factor halves the answer.

What is 810 times 0?

0. Any number multiplied by zero is zero, because zero groups of 810 contain nothing.

What is 810 × 7 and 810 × 8?

810 × 7 = 5,670 and 810 × 8 = 6,480. These two are the facts most people find hardest, so they are worth practising on their own.

Is 12,150 in the 810 times table?

Yes: 12,150 ÷ 810 = 15 with no remainder. 12,151 is not, because dividing it by 810 leaves a remainder of 1.

How do I learn the 810 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.
