The 13 times table from 1 to 20

13 sits beyond the standard 12 × 12 chart, but its multiples come up constantly — a baker’s dozen is 13. Each row also gives the division fact it answers.

Patterns in the 13 times table

• Last digits. The ones digits of 13 × 1 to 13 × 10 are 3, 6, 9, 2, 5, 8, 1, 4, 7, 0 — all ten digits appear once before the pattern repeats, because 13 shares no factor with 10.
• Odd and even. 13 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 (13 × 1 to 13 × 9 give 4, 8, 3, 7, 2, 6, 1, 5, 9) and all nine values appear before repeating.
• A prime table. 13 is prime, so its table cannot be built by chaining smaller tables — split it instead: 13 × k = 10 × k + 3 × k.

A shortcut for multiplying by 13

Ten times plus three times: 13 × 6 = 60 + 18 = 78.

Worked example: 13 × 7

Split 13 into 10 + 3: 10 × 7 = 70 and 3 × 7 = 21, so 13 × 7 = 91.
