Patterns that help you remember it

  • The last digits repeat in a cycle of 1: 0.
  • Every answer is even, because 170 is even.
  • Every answer ends in 0 or 5.
  • Split it into tens and ones: 170 × k = 170 × k + 0 × k.
  • Each answer is 170 more than the one before, so you can count on in steps of 170.

Building it from tables you already know

Every answer in the 170 times table is double the answer in the 85 times table: 85 × 6 = 510, so 170 × 6 = 1,020. To multiply 170 by 9, multiply by 10 and take one 170 away: 1,700 − 170 = 1,530. To multiply by 11, multiply by 10 and add one more 170: 1,700 + 170 = 1,870. Multiplying by 4 is doubling twice: 170 → 340 → 680.

Every multiple of 170 is at least 170, so there are none below 100 and 5 below 1,000. A number is in the 170 times table exactly when it divides by 170 with no remainder.

Odd, even and the last digit

Because 170 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: 170 × 10 = 1,700, and 170 × 100 = 17,000. Multiplying by 5 is half of multiplying by 10: half of 1,700 is 850.

Using the 170 times table to divide

Every fact also works backwards: because 170 × 7 = 1,190, you know 1,190 ÷ 170 = 7 and 1,190 ÷ 7 = 170. 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:

  1. A box holds 170 pencils. How many pencils are in 5 boxes?
    Answer5 × 170 = 850 pencils.
  2. Tickets cost $170 each. How much do 6 tickets cost?
    Answer6 × $170 = $1,020.
  3. 850 chairs are set out in rows of 170. How many rows are there?
    Answer850 ÷ 170 = 5 rows.
  4. A plant grows 170 millimetres a week. How much does it grow in 6 weeks?

Questions

What is 170 × 12?

2,040.

What is half of 170 × 8?

170 × 8 = 1,360, and half of that is 680, which is 170 × 4. Halving one factor halves the answer.

What is 170 times 0?

0. Any number multiplied by zero is zero, because zero groups of 170 contain nothing.

What is 170 × 7 and 170 × 8?

170 × 7 = 1,190 and 170 × 8 = 1,360. These two are the facts most people find hardest, so they are worth practising on their own.

Is 2,550 in the 170 times table?

Yes: 2,550 ÷ 170 = 15 with no remainder. 2,551 is not, because dividing it by 170 leaves a remainder of 1.

How do I learn the 170 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.
