The 23 times table from 1 to 20
23 sits beyond the standard 12 × 12 chart, but its multiples come up constantly — a human body cell has 23 pairs of chromosomes. Each row also gives the division fact it answers.
| Fact | Answer | Division fact |
|---|---|---|
| 23 × 1 | 23 | 23 ÷ 23 = 1 |
| 23 × 2 | 46 | 46 ÷ 23 = 2 |
| 23 × 3 | 69 | 69 ÷ 23 = 3 |
| 23 × 4 | 92 | 92 ÷ 23 = 4 |
| 23 × 5 | 115 | 115 ÷ 23 = 5 |
| 23 × 6 | 138 | 138 ÷ 23 = 6 |
| 23 × 7 | 161 | 161 ÷ 23 = 7 |
| 23 × 8 | 184 | 184 ÷ 23 = 8 |
| 23 × 9 | 207 | 207 ÷ 23 = 9 |
| 23 × 10 | 230 | 230 ÷ 23 = 10 |
| 23 × 11 | 253 | 253 ÷ 23 = 11 |
| 23 × 12 | 276 | 276 ÷ 23 = 12 |
| 23 × 13 | 299 | 299 ÷ 23 = 13 |
| 23 × 14 | 322 | 322 ÷ 23 = 14 |
| 23 × 15 | 345 | 345 ÷ 23 = 15 |
| 23 × 16 | 368 | 368 ÷ 23 = 16 |
| 23 × 17 | 391 | 391 ÷ 23 = 17 |
| 23 × 18 | 414 | 414 ÷ 23 = 18 |
| 23 × 19 | 437 | 437 ÷ 23 = 19 |
| 23 × 20 | 460 | 460 ÷ 23 = 20 |
Patterns in the 23 times table
- Last digits. The ones digits of 23 × 1 to 23 × 10 are 3, 6, 9, 2, 5, 8, 1, 4, 7, 0 — all ten digits appear once before the pattern repeats, because 23 shares no factor with 10.
- Odd and even. 23 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 (23 × 1 to 23 × 9 give 5, 1, 6, 2, 7, 3, 8, 4, 9) and all nine values appear before repeating.
- A prime table. 23 is prime, so its table cannot be built by chaining smaller tables — split it instead: 23 × k = 10 × k + 13 × k.
A shortcut for multiplying by 23
Twenty times plus three times: 23 × 7 = 140 + 21 = 161.
Worked example: 23 × 7
Split 23 into 10 + 13: 10 × 7 = 70 and 13 × 7 = 91, so 23 × 7 = 161.

Frequently asked questions
What is the 23 times table up to 12?
23 × 1 = 23, 23 × 2 = 46, 23 × 3 = 69, 23 × 4 = 92, 23 × 5 = 115, 23 × 6 = 138, 23 × 7 = 161, 23 × 8 = 184, 23 × 9 = 207, 23 × 10 = 230, 23 × 11 = 253, 23 × 12 = 276.
What is the easiest way to learn the 23 times table?
Twenty times plus three times: 23 × 7 = 140 + 21 = 161.
What is 23 times 20?
23 × 20 = 460. Multiply 23 by 2 to get 46, then write a zero on the end.
Where is the 23 times table used in real life?
Any time you count equal groups of 23: a human body cell has 23 pairs of chromosomes, so the chromosome pairs in several human body cells come straight from the 23 times table.
