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: 221 × k = 220 × k + 1 × k.
  • Each answer is 221 more than the one before, so you can count on in steps of 221.

Building it from tables you already know

To multiply 221 by 9, multiply by 10 and take one 221 away: 2,210 − 221 = 1,989. To multiply by 11, multiply by 10 and add one more 221: 2,210 + 221 = 2,431. Multiplying by 4 is doubling twice: 221 → 442 → 884.

Every multiple of 221 is at least 221, so there are none below 100 and 4 below 1,000. A number is in the 221 times table exactly when it divides by 221 with no remainder.

Odd, even and the last digit

Because 221 is odd, the answers alternate between odd and even: 221 × 1 = 221 is odd, 221 × 2 = 442 is even, and so on. Multiplying by 10 always puts a zero on the end: 221 × 10 = 2,210, and 221 × 100 = 22,100. Multiplying by 5 is half of multiplying by 10: half of 2,210 is 1,105.

Using the 221 times table to divide

Every fact also works backwards: because 221 × 7 = 1,547, you know 1,547 ÷ 221 = 7 and 1,547 ÷ 7 = 221. 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:

  1. A box holds 221 pencils. How many pencils are in 8 boxes?
    Answer8 × 221 = 1,768 pencils.
  2. Tickets cost $221 each. How much do 11 tickets cost?
    Answer11 × $221 = $2,431.
  3. 663 chairs are set out in rows of 221. How many rows are there?
    Answer663 ÷ 221 = 3 rows.
  4. A plant grows 221 millimetres a week. How much does it grow in 6 weeks?
    Answer6 × 221 = 1,326 millimetres.

Questions

What is 221 × 12?

2,652.

What is half of 221 × 8?

221 × 8 = 1,768, and half of that is 884, which is 221 × 4. Halving one factor halves the answer.

What is 221 times 0?

0. Any number multiplied by zero is zero, because zero groups of 221 contain nothing.

What is 221 × 7 and 221 × 8?

221 × 7 = 1,547 and 221 × 8 = 1,768. These two are the facts most people find hardest, so they are worth practising on their own.

Is 3,315 in the 221 times table?

Yes: 3,315 ÷ 221 = 15 with no remainder. 3,316 is not, because dividing it by 221 leaves a remainder of 1.

How do I learn the 221 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.
