Patterns that help you remember it

  • The last digits repeat in a cycle of 1: 0.
  • Every answer is even, because 280 is even.
  • Every answer ends in 0 or 5.
  • Split it into tens and ones: 280 × k = 280 × k + 0 × k.
  • Each answer is 280 more than the one before, so you can count on in steps of 280.

Building it from tables you already know

Every answer in the 280 times table is double the answer in the 140 times table: 140 × 6 = 840, so 280 × 6 = 1,680. To multiply 280 by 9, multiply by 10 and take one 280 away: 2,800 − 280 = 2,520. To multiply by 11, multiply by 10 and add one more 280: 2,800 + 280 = 3,080. Multiplying by 4 is doubling twice: 280 → 560 → 1,120.

Every multiple of 280 is at least 280, so there are none below 100 and 3 below 1,000. A number is in the 280 times table exactly when it divides by 280 with no remainder.

Odd, even and the last digit

Because 280 is even, every answer in its table is even, which is a quick way to catch a wrong answer. Multiplying by 10 always puts a zero on the end: 280 × 10 = 2,800, and 280 × 100 = 28,000. Multiplying by 5 is half of multiplying by 10: half of 2,800 is 1,400.

Using the 280 times table to divide

Every fact also works backwards: because 280 × 7 = 1,960, you know 1,960 ÷ 280 = 7 and 1,960 ÷ 7 = 280. 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:

    Answer4 × 280 = 1,120 pencils.
  2. Tickets cost $280 each. How much do 7 tickets cost?
    Answer7 × $280 = $1,960.
  3. 560 chairs are set out in rows of 280. How many rows are there?
    Answer560 ÷ 280 = 2 rows.
  4. A plant grows 280 millimetres a week. How much does it grow in 6 weeks?

Questions

What is 280 × 12?

3,360.

What is half of 280 × 8?

280 × 8 = 2,240, and half of that is 1,120, which is 280 × 4. Halving one factor halves the answer.

What is 280 times 0?

0. Any number multiplied by zero is zero, because zero groups of 280 contain nothing.

What is 280 × 7 and 280 × 8?

280 × 7 = 1,960 and 280 × 8 = 2,240. These two are the facts most people find hardest, so they are worth practising on their own.

Is 4,200 in the 280 times table?

Yes: 4,200 ÷ 280 = 15 with no remainder. 4,201 is not, because dividing it by 280 leaves a remainder of 1.

How do I learn the 280 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.
