What 36 is made of
Every common factor 36 can share with anything comes from this list, which is why the pairs below look the way they do. 36 = 2² × 3², and that factorisation is unique — the fundamental theorem of arithmetic guarantees no other set of primes multiplies to it.
- Divisors (9)
- 1, 2, 3, 4, 6, 9, 12, 18, 36
- As factor pairs
- 1×36, 2×18, 3×12, 4×9, 6×6
- Prime factorisation
- 2² × 3²
- Divisors excluding itself add to
- 55 — abundant
36 is a perfect square, so it has an odd number of divisors — the square root pairs with itself. The greatest common factor of 36 and any other number is the largest entry two lists like this one share.
