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: 121 × k = 120 × k + 1 × k.
- Each answer is 121 more than the one before, so you can count on in steps of 121.
Building it from tables you already know
To multiply 121 by 9, multiply by 10 and take one 121 away: 1,210 − 121 = 1,089. To multiply by 11, multiply by 10 and add one more 121: 1,210 + 121 = 1,331. Multiplying by 4 is doubling twice: 121 → 242 → 484.
Every multiple of 121 is at least 121, so there are none below 100 and 8 below 1,000. A number is in the 121 times table exactly when it divides by 121 with no remainder.
Odd, even and the last digit
Because 121 is odd, the answers alternate between odd and even: 121 × 1 = 121 is odd, 121 × 2 = 242 is even, and so on. Multiplying by 10 always puts a zero on the end: 121 × 10 = 1,210, and 121 × 100 = 12,100. Multiplying by 5 is half of multiplying by 10: half of 1,210 is 605.
Using the 121 times table to divide
Every fact also works backwards: because 121 × 7 = 847, you know 847 ÷ 121 = 7 and 847 ÷ 7 = 121. 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 121 pencils. How many pencils are in 9 boxes?
Answer
9 × 121 = 1,089 pencils. - Tickets cost $121 each. How much do 6 tickets cost?
Answer
6 × $121 = $726. - 363 chairs are set out in rows of 121. How many rows are there?
Answer
363 ÷ 121 = 3 rows. - A plant grows 121 millimetres a week. How much does it grow in 6 weeks?
Answer
6 × 121 = 726 millimetres.
Questions
What is 121 × 12?
1,452.
What is half of 121 × 8?
121 × 8 = 968, and half of that is 484, which is 121 × 4. Halving one factor halves the answer.
What is 121 times 0?
0. Any number multiplied by zero is zero, because zero groups of 121 contain nothing.
What is 121 × 7 and 121 × 8?
121 × 7 = 847 and 121 × 8 = 968. These two are the facts most people find hardest, so they are worth practising on their own.
Is 1,815 in the 121 times table?
Yes: 1,815 ÷ 121 = 15 with no remainder. 1,816 is not, because dividing it by 121 leaves a remainder of 1.
How do I learn the 121 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.
