The 21 times table from 1 to 20

21 sits beyond the standard 12 × 12 chart, but its multiples come up constantly — the six faces of a die carry 1 + 2 + 3 + 4 + 5 + 6 = 21 pips. Each row also gives the division fact it answers.

21 × 17	357	357 ÷ 21 = 17
21 × 18	378	378 ÷ 21 = 18

Patterns in the 21 times table

Last digits. The ones digits of 21 × 1 to 21 × 10 are 1, 2, 3, 4, 5, 6, 7, 8, 9, 0 — all ten digits appear once before the pattern repeats, because 21 shares no factor with 10.
Odd and even. 21 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 by adding its digits and you get 3, 6, 9, repeating — a sign that every answer is a multiple of 3.
Built from smaller tables. 21 = 3 × 7, so you can multiply by 3 and then by 7: 21 × 7 = 7 × 21 = 147.
Split by place value. 21 × k = 10 × k + 11 × k, so 21 × 13 = 130 + 143 = 273.

A shortcut for multiplying by 21

Twenty times plus once: 21 × 6 = 120 + 6 = 126.

Worked example: 21 × 7

Split 21 into 10 + 11: 10 × 7 = 70 and 11 × 7 = 77, so 21 × 7 = 147.

For a self-checking quiz with new questions every time, use the practice mode of the multiplication table.

21 × 21 = 441, so the square root of 441 is 21.
The factors of 21 are 1, 3, 7 and 21; they pair up as 1 × 21 and 3 × 7, so 21 appears as an answer in each of those tables.
Every answer in this table is a multiple of 21; the multiples calculator lists them past × 20.
