The 17 times table from 1 to 20

17 sits beyond the standard 12 × 12 chart, but its multiples come up constantly — a traditional haiku has 17 syllables (5 + 7 + 5). Each row also gives the division fact it answers.

Patterns in the 17 times table

• Last digits. The ones digits of 17 × 1 to 17 × 10 are 7, 4, 1, 8, 5, 2, 9, 6, 3, 0 — all ten digits appear once before the pattern repeats, because 17 shares no factor with 10.
• Odd and even. 17 is odd, so the answers alternate odd, even, odd, even — odd times odd is odd, odd times even is even.
• Digit sums. Reduce each answer to a single digit (17 × 1 to 17 × 9 give 8, 7, 6, 5, 4, 3, 2, 1, 9) and all nine values appear before repeating.
• A prime table. 17 is prime, so its table cannot be built by chaining smaller tables — split it instead: 17 × k = 10 × k + 7 × k.

A shortcut for multiplying by 17

Twenty times minus three times: 17 × 6 = 120 − 18 = 102.

Worked example: 17 × 7

Split 17 into 10 + 7: 10 × 7 = 70 and 7 × 7 = 49, so 17 × 7 = 119.
