Patterns that help you remember it
- The last digits repeat in a cycle of 10: 7, 4, 1, 8, 5, 2, 9, 6, 3, 0.
- The digits of every answer add up to a multiple of 9.
- Split it into tens and ones: 1287 × k = 1280 × k + 7 × k.
- Each answer is 1287 more than the one before, so you can count on in steps of 1287.
Building it from tables you already know
To multiply 1287 by 9, multiply by 10 and take one 1287 away: 12,870 − 1287 = 11,583. To multiply by 11, multiply by 10 and add one more 1287: 12,870 + 1287 = 14,157. Multiplying by 4 is doubling twice: 1287 → 2,574 → 5,148.
Every multiple of 1287 is at least 1287, so there are none below 100 and 0 below 1,000. A number is in the 1287 times table exactly when it divides by 1287 with no remainder.
Odd, even and the last digit
Because 1287 is odd, the answers alternate between odd and even: 1287 × 1 = 1287 is odd, 1287 × 2 = 2,574 is even, and so on. Multiplying by 10 always puts a zero on the end: 1287 × 10 = 12,870, and 1287 × 100 = 128,700. Multiplying by 5 is half of multiplying by 10: half of 12,870 is 6,435.
Using the 1287 times table to divide
Every fact also works backwards: because 1287 × 7 = 9,009, you know 9,009 ÷ 1287 = 7 and 9,009 ÷ 7 = 1287. 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 1287 pencils. How many pencils are in 3 boxes?
Answer
3 × 1287 = 3,861 pencils. - Tickets cost $1287 each. How much do 11 tickets cost?
Answer
11 × $1287 = $14,157. - 5,148 chairs are set out in rows of 1287. How many rows are there?
Answer
5,148 ÷ 1287 = 4 rows. - A plant grows 1287 millimetres a week. How much does it grow in 6 weeks?
Answer
6 × 1287 = 7,722 millimetres.
Questions
What is 1287 × 12?
15,444.
What is half of 1287 × 8?
1287 × 8 = 10,296, and half of that is 5,148, which is 1287 × 4. Halving one factor halves the answer.
What is 1287 times 0?
0. Any number multiplied by zero is zero, because zero groups of 1287 contain nothing.
What is 1287 × 7 and 1287 × 8?
1287 × 7 = 9,009 and 1287 × 8 = 10,296. These two are the facts most people find hardest, so they are worth practising on their own.
Is 19,305 in the 1287 times table?
Yes: 19,305 ÷ 1287 = 15 with no remainder. 19,306 is not, because dividing it by 1287 leaves a remainder of 1.
How do I learn the 1287 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.
