    Is 274 a prime or composite number?

    Answer

    Number 274 is not a Prime

    274 = 2 × 137

    274 has 4 divisors — 1, 2, 137 and 274; a prime has exactly two: 1 and itself.

    Primes up to √274

    16² = 256 ≤ 274 < 289 = 17², so it is enough to try primes up to 16

    • ÷2 divides

    274 ÷ 2 = 137 — 2 divides 274, so 274 is composite

    Nearest primes: 271 and 277
