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: 631 × k = 630 × k + 1 × k.
- Each answer is 631 more than the one before, so you can count on in steps of 631.
Building it from tables you already know
To multiply 631 by 9, multiply by 10 and take one 631 away: 6,310 − 631 = 5,679. To multiply by 11, multiply by 10 and add one more 631: 6,310 + 631 = 6,941. Multiplying by 4 is doubling twice: 631 → 1,262 → 2,524.
Every multiple of 631 is at least 631, so there are none below 100 and 1 below 1,000. A number is in the 631 times table exactly when it divides by 631 with no remainder.
Odd, even and the last digit
Because 631 is odd, the answers alternate between odd and even: 631 × 1 = 631 is odd, 631 × 2 = 1,262 is even, and so on. Multiplying by 10 always puts a zero on the end: 631 × 10 = 6,310, and 631 × 100 = 63,100. Multiplying by 5 is half of multiplying by 10: half of 6,310 is 3,155.
Using the 631 times table to divide
Every fact also works backwards: because 631 × 7 = 4,417, you know 4,417 ÷ 631 = 7 and 4,417 ÷ 7 = 631. 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 631 pencils. How many pencils are in 3 boxes?
Answer
3 × 631 = 1,893 pencils. - Tickets cost $631 each. How much do 8 tickets cost?
Answer
8 × $631 = $5,048. - 3,786 chairs are set out in rows of 631. How many rows are there?
Answer
3,786 ÷ 631 = 6 rows. - A plant grows 631 millimetres a week. How much does it grow in 10 weeks?
Answer
10 × 631 = 6,310 millimetres.
Questions
What is 631 × 12?
7,572.
What is half of 631 × 8?
631 × 8 = 5,048, and half of that is 2,524, which is 631 × 4. Halving one factor halves the answer.
What is 631 times 0?
0. Any number multiplied by zero is zero, because zero groups of 631 contain nothing.
What is 631 × 7 and 631 × 8?
631 × 7 = 4,417 and 631 × 8 = 5,048. These two are the facts most people find hardest, so they are worth practising on their own.
Is 9,465 in the 631 times table?
Yes: 9,465 ÷ 631 = 15 with no remainder. 9,466 is not, because dividing it by 631 leaves a remainder of 1.
How do I learn the 631 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.
