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: 1221 × k = 1220 × k + 1 × k.
- Each answer is 1221 more than the one before, so you can count on in steps of 1221.
Building it from tables you already know
To multiply 1221 by 9, multiply by 10 and take one 1221 away: 12,210 − 1221 = 10,989. To multiply by 11, multiply by 10 and add one more 1221: 12,210 + 1221 = 13,431. Multiplying by 4 is doubling twice: 1221 → 2,442 → 4,884.
Every multiple of 1221 is at least 1221, so there are none below 100 and 0 below 1,000. A number is in the 1221 times table exactly when it divides by 1221 with no remainder.
Odd, even and the last digit
Because 1221 is odd, the answers alternate between odd and even: 1221 × 1 = 1221 is odd, 1221 × 2 = 2,442 is even, and so on. Multiplying by 10 always puts a zero on the end: 1221 × 10 = 12,210, and 1221 × 100 = 122,100. Multiplying by 5 is half of multiplying by 10: half of 12,210 is 6,105.
Using the 1221 times table to divide
Every fact also works backwards: because 1221 × 7 = 8,547, you know 8,547 ÷ 1221 = 7 and 8,547 ÷ 7 = 1221. 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 1221 pencils. How many pencils are in 6 boxes?
Answer
6 × 1221 = 7,326 pencils. - Tickets cost $1221 each. How much do 10 tickets cost?
Answer
10 × $1221 = $12,210. - 2,442 chairs are set out in rows of 1221. How many rows are there?
Answer
2,442 ÷ 1221 = 2 rows. - A plant grows 1221 millimetres a week. How much does it grow in 10 weeks?
Answer
10 × 1221 = 12,210 millimetres.
Questions
What is 1221 × 12?
14,652.
What is half of 1221 × 8?
1221 × 8 = 9,768, and half of that is 4,884, which is 1221 × 4. Halving one factor halves the answer.
What is 1221 times 0?
0. Any number multiplied by zero is zero, because zero groups of 1221 contain nothing.
What is 1221 × 7 and 1221 × 8?
1221 × 7 = 8,547 and 1221 × 8 = 9,768. These two are the facts most people find hardest, so they are worth practising on their own.
Is 18,315 in the 1221 times table?
Yes: 18,315 ÷ 1221 = 15 with no remainder. 18,316 is not, because dividing it by 1221 leaves a remainder of 1.
How do I learn the 1221 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.
