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.
  • Split it into tens and ones: 503 × k = 500 × k + 3 × k.
  • Each answer is 503 more than the one before, so you can count on in steps of 503.

Building it from tables you already know

To multiply 503 by 9, multiply by 10 and take one 503 away: 5,030 − 503 = 4,527. To multiply by 11, multiply by 10 and add one more 503: 5,030 + 503 = 5,533. Multiplying by 4 is doubling twice: 503 → 1,006 → 2,012.

Every multiple of 503 is at least 503, so there are none below 100 and 1 below 1,000. A number is in the 503 times table exactly when it divides by 503 with no remainder.

Odd, even and the last digit

Because 503 is odd, the answers alternate between odd and even: 503 × 1 = 503 is odd, 503 × 2 = 1,006 is even, and so on. Multiplying by 10 always puts a zero on the end: 503 × 10 = 5,030, and 503 × 100 = 50,300. Multiplying by 5 is half of multiplying by 10: half of 5,030 is 2,515.

Using the 503 times table to divide

Every fact also works backwards: because 503 × 7 = 3,521, you know 3,521 ÷ 503 = 7 and 3,521 ÷ 7 = 503. Practising the table and its division facts together halves the work.

Questions

What is 503 × 12?

6,036.

What is half of 503 × 8?

503 × 8 = 4,024, and half of that is 2,012, which is 503 × 4. Halving one factor halves the answer.

What is 503 times 0?

0. Any number multiplied by zero is zero, because zero groups of 503 contain nothing.

What is 503 × 7 and 503 × 8?

503 × 7 = 3,521 and 503 × 8 = 4,024. These two are the facts most people find hardest, so they are worth practising on their own.

Is 7,545 in the 503 times table?

Yes: 7,545 ÷ 503 = 15 with no remainder. 7,546 is not, because dividing it by 503 leaves a remainder of 1.

How do I learn the 503 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.
