    Is 297 a prime or composite number?

    Answer

    Number 297 is not a Prime

    297 = 3³ × 11

    297 has 8 divisors — 1, 3, 9, 11, 27, 33, 99 and 297; a prime has exactly two: 1 and itself.

    Primes up to √297

    17² = 289 ≤ 297 < 324 = 18², so it is enough to try primes up to 17

    • ÷2 does not divide
    • ÷3 divides

    297 ÷ 3 = 99 — 3 divides 297, so 297 is composite

    Nearest primes: 293 and 307
