Is 250 a prime or composite number?

Answer

Number 250 is not a Prime

250 = 2 × 5³

250 has 8 divisors — 1, 2, 5, 10, 25, 50, 125 and 250; a prime has exactly two: 1 and itself.

Primes up to √250

15² = 225 ≤ 250 < 256 = 16², so it is enough to try primes up to 15

  • ÷2 divides

250 ÷ 2 = 125 — 2 divides 250, so 250 is composite

Nearest primes: 241 and 251
