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: 91 × k = 90 × k + 1 × k.
- Each answer is 91 more than the one before, so you can count on in steps of 91.
Building it from tables you already know
To multiply 91 by 9, multiply by 10 and take one 91 away: 910 − 91 = 819. To multiply by 11, multiply by 10 and add one more 91: 910 + 91 = 1,001. Multiplying by 4 is doubling twice: 91 → 182 → 364.
There are 1 multiples of 91 below 100, and 10 below 1,000. A number is in the 91 times table exactly when it divides by 91 with no remainder.
Odd, even and the last digit
Because 91 is odd, the answers alternate between odd and even: 91 × 1 = 91 is odd, 91 × 2 = 182 is even, and so on. Multiplying by 10 always puts a zero on the end: 91 × 10 = 910, and 91 × 100 = 9,100. Multiplying by 5 is half of multiplying by 10: half of 910 is 455.
Using the 91 times table to divide
Every fact also works backwards: because 91 × 7 = 637, you know 637 ÷ 91 = 7 and 637 ÷ 7 = 91. 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 91 pencils. How many pencils are in 8 boxes?
Answer
8 × 91 = 728 pencils. - Tickets cost $91 each. How much do 5 tickets cost?
Answer
5 × $91 = $455. - 819 chairs are set out in rows of 91. How many rows are there?
Answer
819 ÷ 91 = 9 rows. - A plant grows 91 millimetres a week. How much does it grow in 6 weeks?
Answer
6 × 91 = 546 millimetres.
Questions
What is 91 × 12?
1,092.
What is half of 91 × 8?
91 × 8 = 728, and half of that is 364, which is 91 × 4. Halving one factor halves the answer.
What is 91 times 0?
0. Any number multiplied by zero is zero, because zero groups of 91 contain nothing.
What is 91 × 7 and 91 × 8?
91 × 7 = 637 and 91 × 8 = 728. These two are the facts most people find hardest, so they are worth practising on their own.
Is 1,365 in the 91 times table?
Yes: 1,365 ÷ 91 = 15 with no remainder. 1,366 is not, because dividing it by 91 leaves a remainder of 1.
How do I learn the 91 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.
