Patterns that help you remember it

  • The last digits repeat in a cycle of 2: 5, 0.
  • Every answer ends in 0 or 5.
  • Split it into tens and ones: 345 × k = 340 × k + 5 × k.
  • Each answer is 345 more than the one before, so you can count on in steps of 345.

Building it from tables you already know

To multiply 345 by 9, multiply by 10 and take one 345 away: 3,450 − 345 = 3,105. To multiply by 11, multiply by 10 and add one more 345: 3,450 + 345 = 3,795. Multiplying by 4 is doubling twice: 345 → 690 → 1,380.

Every multiple of 345 is at least 345, so there are none below 100 and 2 below 1,000. A number is in the 345 times table exactly when it divides by 345 with no remainder.

Odd, even and the last digit

Because 345 is odd, the answers alternate between odd and even: 345 × 1 = 345 is odd, 345 × 2 = 690 is even, and so on. Multiplying by 10 always puts a zero on the end: 345 × 10 = 3,450, and 345 × 100 = 34,500. Multiplying by 5 is half of multiplying by 10: half of 3,450 is 1,725.

Using the 345 times table to divide

Every fact also works backwards: because 345 × 7 = 2,415, you know 2,415 ÷ 345 = 7 and 2,415 ÷ 7 = 345. Practising the table and its division facts together halves the work.

Questions

What is 345 × 12?

4,140.

What is half of 345 × 8?

345 × 8 = 2,760, and half of that is 1,380, which is 345 × 4. Halving one factor halves the answer.

What is 345 times 0?

0. Any number multiplied by zero is zero, because zero groups of 345 contain nothing.

What is 345 × 7 and 345 × 8?

345 × 7 = 2,415 and 345 × 8 = 2,760. These two are the facts most people find hardest, so they are worth practising on their own.

Is 5,175 in the 345 times table?

Yes: 5,175 ÷ 345 = 15 with no remainder. 5,176 is not, because dividing it by 345 leaves a remainder of 1.

How do I learn the 345 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.
