Factors of 34
Every whole number that divides 34 exactly, the factor pairs, and how to find them yourself.
The answer
The factors of 34 are 1, 2, 17 and 34.
Factor pairs of 34
| Pair | Makes |
|---|---|
| 1 × 34 | 34 |
| 2 × 17 | 34 |
Prime factors of 34
- Prime factorisation
- 34 = 2 × 17
- Is 34 prime?
- No. It has 4 factors, not just 1 and 34.
- Is 34 a square number?
- No. 5 × 5 = 25 and 6 × 6 = 36, so 34 falls between two square numbers.
How to find the factors of 34
34 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.
- 34 ÷ 1 = 34, so 1 × 34 is a pair.
- 34 ÷ 2 = 17, so 2 × 17 is a pair.
- 3 does not go into 34 exactly.
- 4 does not go into 34 exactly.
- 5 does not go into 34 exactly.
Stop at 6: 6 × 6 = 36, which is more than 34. The next pair you would find is 17 × 2, which is 2 × 17 turned round, so you already have every pair.
