Is 264 a prime or composite number?

Answer

Number 264 is not a Prime

264 = 2³ × 3 × 11

264 has 16 divisors, not two: a prime is divisible only by 1 and itself.

Primes up to √264

16² = 256 ≤ 264 < 289 = 17², so it is enough to try primes up to 16

  • ÷2 divides

264 ÷ 2 = 132 — 2 divides 264, so 264 is composite

Nearest primes: 263 and 269
