Patterns that help you remember it
- The last digits repeat in a cycle of 10: 9, 8, 7, 6, 5, 4, 3, 2, 1, 0.
- The digits of every answer add up to a multiple of 9.
- Split it into tens and ones: 819 × k = 810 × k + 9 × k.
- Each answer is 819 more than the one before, so you can count on in steps of 819.
Building it from tables you already know
To multiply 819 by 9, multiply by 10 and take one 819 away: 8,190 − 819 = 7,371. To multiply by 11, multiply by 10 and add one more 819: 8,190 + 819 = 9,009. Multiplying by 4 is doubling twice: 819 → 1,638 → 3,276.
Every multiple of 819 is at least 819, so there are none below 100 and 1 below 1,000. A number is in the 819 times table exactly when it divides by 819 with no remainder.
Odd, even and the last digit
Because 819 is odd, the answers alternate between odd and even: 819 × 1 = 819 is odd, 819 × 2 = 1,638 is even, and so on. Multiplying by 10 always puts a zero on the end: 819 × 10 = 8,190, and 819 × 100 = 81,900. Multiplying by 5 is half of multiplying by 10: half of 8,190 is 4,095.
Using the 819 times table to divide
Every fact also works backwards: because 819 × 7 = 5,733, you know 5,733 ÷ 819 = 7 and 5,733 ÷ 7 = 819. 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:
- A box holds 819 pencils. How many pencils are in 8 boxes?
Answer
8 × 819 = 6,552 pencils. - Tickets cost $819 each. How much do 8 tickets cost?
Answer
8 × $819 = $6,552. - 2,457 chairs are set out in rows of 819. How many rows are there?
Answer
2,457 ÷ 819 = 3 rows. - A plant grows 819 millimetres a week. How much does it grow in 9 weeks?
Answer
9 × 819 = 7,371 millimetres.
Questions
What is 819 × 12?
9,828.
What is half of 819 × 8?
819 × 8 = 6,552, and half of that is 3,276, which is 819 × 4. Halving one factor halves the answer.
What is 819 times 0?
0. Any number multiplied by zero is zero, because zero groups of 819 contain nothing.
What is 819 × 7 and 819 × 8?
819 × 7 = 5,733 and 819 × 8 = 6,552. These two are the facts most people find hardest, so they are worth practising on their own.
Is 12,285 in the 819 times table?
Yes: 12,285 ÷ 819 = 15 with no remainder. 12,286 is not, because dividing it by 819 leaves a remainder of 1.
How do I learn the 819 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.
