Is 50 a prime or composite number?

Answer

Number 50 is not a Prime

50 = 2 × 5²

50 has 6 divisors — 1, 2, 5, 10, 25 and 50; a prime has exactly two: 1 and itself.

Primes up to √50

7² = 49 ≤ 50 < 64 = 8², so it is enough to try primes up to 7

  • ÷2 divides

50 ÷ 2 = 25 — 2 divides 50, so 50 is composite

Nearest primes: 47 and 53

How to check if 50 is prime?

Divide 50 by the primes in order: 7² = 49 ≤ 50 < 64 = 8², so it is enough to try primes up to 7. The first one that divides it is 2: 50 ÷ 2 = 25, so 50 is composite.
