    Is 234 a prime or composite number?

    Answer

    Number 234 is not a Prime

    234 = 2 × 3² × 13

    234 has 12 divisors, not two: a prime is divisible only by 1 and itself.

    Primes up to √234

    15² = 225 ≤ 234 < 256 = 16², so it is enough to try primes up to 15

    • ÷2 divides

    234 ÷ 2 = 117 — 2 divides 234, so 234 is composite

    Nearest primes: 233 and 239
