Is 597 a prime or composite number?

Answer

Number 597 is not a Prime

597 = 3 × 199

597 has 4 divisors — 1, 3, 199 and 597; a prime has exactly two: 1 and itself.

Primes up to √597

24² = 576 ≤ 597 < 625 = 25², so it is enough to try primes up to 24

÷2 does not divide
÷3 divides

597 ÷ 3 = 199 — 3 divides 597, so 597 is composite

Nearest primes: 593 and 599
