Shares a factor with 50

What 50 is made of

Every common factor 50 can share with anything comes from this list, which is why the pairs below look the way they do. 50 = 2 × 5², and that factorisation is unique — the fundamental theorem of arithmetic guarantees no other set of primes multiplies to it.

Divisors (6)
1, 2, 5, 10, 25, 50
As factor pairs
1×50, 2×25, 5×10
Prime factorisation

Divisors excluding itself add to
43 — deficient

Divisors come in pairs that multiply to 50, which is why there is an even number of them unless the number is a perfect square. The greatest common factor of 50 and any other number is the largest entry two lists like this one share.
