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: 181 × k = 180 × k + 1 × k.
- Each answer is 181 more than the one before, so you can count on in steps of 181.
Building it from tables you already know
To multiply 181 by 9, multiply by 10 and take one 181 away: 1,810 − 181 = 1,629. To multiply by 11, multiply by 10 and add one more 181: 1,810 + 181 = 1,991. Multiplying by 4 is doubling twice: 181 → 362 → 724.
Every multiple of 181 is at least 181, so there are none below 100 and 5 below 1,000. A number is in the 181 times table exactly when it divides by 181 with no remainder.
Odd, even and the last digit
Because 181 is odd, the answers alternate between odd and even: 181 × 1 = 181 is odd, 181 × 2 = 362 is even, and so on. Multiplying by 10 always puts a zero on the end: 181 × 10 = 1,810, and 181 × 100 = 18,100. Multiplying by 5 is half of multiplying by 10: half of 1,810 is 905.
Using the 181 times table to divide
Every fact also works backwards: because 181 × 7 = 1,267, you know 1,267 ÷ 181 = 7 and 1,267 ÷ 7 = 181. 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 181 pencils. How many pencils are in 6 boxes?
Answer
6 × 181 = 1,086 pencils. - Tickets cost $181 each. How much do 9 tickets cost?
Answer
9 × $181 = $1,629. - 724 chairs are set out in rows of 181. How many rows are there?
Answer
724 ÷ 181 = 4 rows. - A plant grows 181 millimetres a week. How much does it grow in 6 weeks?
Answer
6 × 181 = 1,086 millimetres.
Questions
What is 181 × 12?
2,172.
What is half of 181 × 8?
181 × 8 = 1,448, and half of that is 724, which is 181 × 4. Halving one factor halves the answer.
What is 181 times 0?
0. Any number multiplied by zero is zero, because zero groups of 181 contain nothing.
What is 181 × 7 and 181 × 8?
181 × 7 = 1,267 and 181 × 8 = 1,448. These two are the facts most people find hardest, so they are worth practising on their own.
Is 2,715 in the 181 times table?
Yes: 2,715 ÷ 181 = 15 with no remainder. 2,716 is not, because dividing it by 181 leaves a remainder of 1.
How do I learn the 181 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.
