17 Times Table
Seventeen is prime, sits far from any round number, and has no doubling shortcut — it is honestly one of the hardest tables on the site. The 10 + 7 split is the reliable way through.
Counting up in 17s: 17, 34, 51, 68, 85, 102, 119, 136, 153, 170

The clever bit
Split 17 into 10 + 7
Seventeen is one of the two genuinely tricky new tables — it is prime, and there is no doubling or halving relationship to lean on. The way through is the same reliable split used for 7 and 13.
Split 17 into 10 + 7:
- 17 × 4 → (10 × 4) + (7 × 4) = 40 + 28 = 68
- 17 × 6 → (10 × 6) + (7 × 6) = 60 + 42 = 102
- 17 × 8 → (10 × 8) + (7 × 8) = 80 + 56 = 136
The 7-times half can use its own trick (5 + 2) if needed, but most children find it faster to just know their 7 times table by this point and use it directly.
The near-ten route for facts close to 17 × 10
- 17 × 9 → 170 − 17 = 153
- 17 × 11 → 170 + 17 = 187
One reassurance
This is meant to be the hardest of the new tables — being slower here is expected, not a sign anything is wrong. The split method always works, even when no shortcut does.
Step one

The ones people trip on
Most mistakes in the 17 times table land on these. Each one has a way in.
17 × 6 = 102
17 × 6 → 10 sixes are 60, 7 sixes are 42, and 60 + 42 = 102.
17 × 8 = 136
17 × 8 → 10 eights are 80, 7 eights are 56, and 80 + 56 = 136.
17 × 9 = 153
17 × 9 → 17 tens are 170, take one 17 away → 153.
Where the 17 times table shows up
Seventeen-year cicadas emerge from the ground once every 17 years — a real example of a prime number showing up in nature. Two broods emerging four years apart would not overlap again for 17 × 4 = 68 years.
Questions parents ask
Why is the 17 times table so hard?
Seventeen is prime, it is not close to 10, 15, or 20 in a way that gives a clean shortcut, and it has no doubling relationship like 14 or 16 do. It genuinely relies more on the split method and practice than the other tables.
What is the 10 plus 7 trick for the 17 times table?
Split 17 into 10 + 7 and multiply separately, then add. For 17 × 6: 10 sixes are 60, 7 sixes are 42, and 60 + 42 = 102. Both halves come from tables already known.
Is there a shortcut for multiplying by 17 near the top of the table?
For facts close to 17 × 10, go via 170 and adjust. 17 × 9 is 170 minus one 17, which is 153. 17 × 11 is 170 plus one 17, which is 187.
What is 17 × 17?
289. Using the split: 10 seventeens are 170, 7 seventeens are 119, and 170 + 119 = 289.
