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: 603 × k = 600 × k + 3 × k.
  • Each answer is 603 more than the one before, so you can count on in steps of 603.

Building it from tables you already know

To multiply 603 by 9, multiply by 10 and take one 603 away: 6,030 − 603 = 5,427. To multiply by 11, multiply by 10 and add one more 603: 6,030 + 603 = 6,633. Multiplying by 4 is doubling twice: 603 → 1,206 → 2,412.

Every multiple of 603 is at least 603, so there are none below 100 and 1 below 1,000. A number is in the 603 times table exactly when it divides by 603 with no remainder.

Odd, even and the last digit

Because 603 is odd, the answers alternate between odd and even: 603 × 1 = 603 is odd, 603 × 2 = 1,206 is even, and so on. Multiplying by 10 always puts a zero on the end: 603 × 10 = 6,030, and 603 × 100 = 60,300. Multiplying by 5 is half of multiplying by 10: half of 6,030 is 3,015.

Using the 603 times table to divide

Every fact also works backwards: because 603 × 7 = 4,221, you know 4,221 ÷ 603 = 7 and 4,221 ÷ 7 = 603. Practising the table and its division facts together halves the work.

    Answer9 × 603 = 5,427 pencils.
  2. Tickets cost $603 each. How much do 12 tickets cost?
    Answer12 × $603 = $7,236.
  3. 3,618 chairs are set out in rows of 603. How many rows are there?
    Answer3,618 ÷ 603 = 6 rows.
  4. A plant grows 603 millimetres a week. How much does it grow in 9 weeks?

Questions

What is 603 × 12?

7,236.

What is half of 603 × 8?

603 × 8 = 4,824, and half of that is 2,412, which is 603 × 4. Halving one factor halves the answer.

What is 603 times 0?

0. Any number multiplied by zero is zero, because zero groups of 603 contain nothing.

What is 603 × 7 and 603 × 8?

603 × 7 = 4,221 and 603 × 8 = 4,824. These two are the facts most people find hardest, so they are worth practising on their own.

Is 9,045 in the 603 times table?

Yes: 9,045 ÷ 603 = 15 with no remainder. 9,046 is not, because dividing it by 603 leaves a remainder of 1.

How do I learn the 603 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.
