Patterns that help you remember it

  • The last digits repeat in a cycle of 10: 3, 6, 9, 2, 5, 8, 1, 4, 7, 0.
  • The digits of every answer add up to a multiple of 9.
  • Split it into tens and ones: 423 × k = 420 × k + 3 × k.
  • Each answer is 423 more than the one before, so you can count on in steps of 423.

Building it from tables you already know

To multiply 423 by 9, multiply by 10 and take one 423 away: 4,230 − 423 = 3,807. To multiply by 11, multiply by 10 and add one more 423: 4,230 + 423 = 4,653. Multiplying by 4 is doubling twice: 423 → 846 → 1,692.

Every multiple of 423 is at least 423, so there are none below 100 and 2 below 1,000. A number is in the 423 times table exactly when it divides by 423 with no remainder.

Odd, even and the last digit

Because 423 is odd, the answers alternate between odd and even: 423 × 1 = 423 is odd, 423 × 2 = 846 is even, and so on. Multiplying by 10 always puts a zero on the end: 423 × 10 = 4,230, and 423 × 100 = 42,300. Multiplying by 5 is half of multiplying by 10: half of 4,230 is 2,115.

Using the 423 times table to divide

Every fact also works backwards: because 423 × 7 = 2,961, you know 2,961 ÷ 423 = 7 and 2,961 ÷ 7 = 423. Practising the table and its division facts together halves the work.

    Answer6 × 423 = 2,538 pencils.
  2. Tickets cost $423 each. How much do 4 tickets cost?
    Answer4 × $423 = $1,692.
  3. 1,692 chairs are set out in rows of 423. How many rows are there?
    Answer1,692 ÷ 423 = 4 rows.
  4. A plant grows 423 millimetres a week. How much does it grow in 8 weeks?

Questions

What is 423 × 12?

5,076.

What is half of 423 × 8?

423 × 8 = 3,384, and half of that is 1,692, which is 423 × 4. Halving one factor halves the answer.

What is 423 times 0?

0. Any number multiplied by zero is zero, because zero groups of 423 contain nothing.

What is 423 × 7 and 423 × 8?

423 × 7 = 2,961 and 423 × 8 = 3,384. These two are the facts most people find hardest, so they are worth practising on their own.

Is 6,345 in the 423 times table?

Yes: 6,345 ÷ 423 = 15 with no remainder. 6,346 is not, because dividing it by 423 leaves a remainder of 1.

How do I learn the 423 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.
