Is 232 a prime or composite number?

Answer

Number 232 is not a Prime

232 = 2³ × 29

232 has 8 divisors — 1, 2, 4, 8, 29, 58, 116 and 232; a prime has exactly two: 1 and itself.

Primes up to √232

15² = 225 ≤ 232 < 256 = 16², so it is enough to try primes up to 15

÷2 divides

232 ÷ 2 = 116 — 2 divides 232, so 232 is composite

Nearest primes: 229 and 233
