    Is 322 a prime or composite number?

    Answer

    Number 322 is not a Prime

    322 = 2 × 7 × 23

    322 has 8 divisors — 1, 2, 7, 14, 23, 46, 161 and 322; a prime has exactly two: 1 and itself.

    Primes up to √322

    17² = 289 ≤ 322 < 324 = 18², so it is enough to try primes up to 17

    • ÷2 divides

    322 ÷ 2 = 161 — 2 divides 322, so 322 is composite

    Nearest primes: 317 and 331
