Factors of 26
Every whole number that divides 26 exactly, the factor pairs, and how to find them yourself.
The answer
The factors of 26 are 1, 2, 13 and 26.
Factor pairs of 26
| Pair | Makes |
|---|---|
| 1 × 26 | 26 |
| 2 × 13 | 26 |
Prime factors of 26
- Prime factorisation
- 26 = 2 × 13
- Is 26 prime?
- No. It has 4 factors, not just 1 and 26.
- Is 26 a square number?
- No. 5 × 5 = 25 and 6 × 6 = 36, so 26 falls between two square numbers.
How to find the factors of 26
26 is even, so 2 is sure to be a factor. Work up from 1 to 5, and write down both numbers in every pair you find.
- 26 ÷ 1 = 26, so 1 × 26 is a pair.
- 26 ÷ 2 = 13, so 2 × 13 is a pair.
- 3 does not go into 26 exactly.
- 4 does not go into 26 exactly.
- 5 does not go into 26 exactly.
Stop at 6: 6 × 6 = 36, which is more than 26. The next pair you would find is 13 × 2, which is 2 × 13 turned round, so you already have every pair.
