What 5 is made of
Every common factor 5 can share with anything comes from this list, which is why the pairs below look the way they do. 5 is prime: its only divisors are 1 and itself, so it shares a factor with another number only when that number is a multiple of it.
- Divisors (2)
- 1, 5
- As factor pairs
- 1×5
- Prime factorisation
- prime
- Divisors excluding itself add to
- 1 — deficient
Divisors come in pairs that multiply to 5, which is why there is an even number of them unless the number is a perfect square. The greatest common factor of 5 and any other number is the largest entry two lists like this one share.
