Patterns that help you remember it
- The last digits repeat in a cycle of 2: 5, 0.
- Every answer ends in 0 or 5.
- Split it into tens and ones: 805 × k = 800 × k + 5 × k.
- Each answer is 805 more than the one before, so you can count on in steps of 805.
Building it from tables you already know
To multiply 805 by 9, multiply by 10 and take one 805 away: 8,050 − 805 = 7,245. To multiply by 11, multiply by 10 and add one more 805: 8,050 + 805 = 8,855. Multiplying by 4 is doubling twice: 805 → 1,610 → 3,220.
Every multiple of 805 is at least 805, so there are none below 100 and 1 below 1,000. A number is in the 805 times table exactly when it divides by 805 with no remainder.
Odd, even and the last digit
Because 805 is odd, the answers alternate between odd and even: 805 × 1 = 805 is odd, 805 × 2 = 1,610 is even, and so on. Multiplying by 10 always puts a zero on the end: 805 × 10 = 8,050, and 805 × 100 = 80,500. Multiplying by 5 is half of multiplying by 10: half of 8,050 is 4,025.
Using the 805 times table to divide
Every fact also works backwards: because 805 × 7 = 5,635, you know 5,635 ÷ 805 = 7 and 5,635 ÷ 7 = 805. 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 805 pencils. How many pencils are in 5 boxes?
Answer
5 × 805 = 4,025 pencils. - Tickets cost $805 each. How much do 7 tickets cost?
Answer
7 × $805 = $5,635. - 2,415 chairs are set out in rows of 805. How many rows are there?
Answer
2,415 ÷ 805 = 3 rows. - A plant grows 805 millimetres a week. How much does it grow in 10 weeks?
Answer
10 × 805 = 8,050 millimetres.
Questions
What is 805 × 12?
9,660.
What is half of 805 × 8?
805 × 8 = 6,440, and half of that is 3,220, which is 805 × 4. Halving one factor halves the answer.
What is 805 times 0?
0. Any number multiplied by zero is zero, because zero groups of 805 contain nothing.
What is 805 × 7 and 805 × 8?
805 × 7 = 5,635 and 805 × 8 = 6,440. These two are the facts most people find hardest, so they are worth practising on their own.
Is 12,075 in the 805 times table?
Yes: 12,075 ÷ 805 = 15 with no remainder. 12,076 is not, because dividing it by 805 leaves a remainder of 1.
How do I learn the 805 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.
