    Is 495 a prime or composite number?

    Answer

    Number 495 is not a Prime

    495 = 3² × 5 × 11

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

    Primes up to √495

    22² = 484 ≤ 495 < 529 = 23², so it is enough to try primes up to 22

    • ÷2 does not divide
    • ÷3 divides

    495 ÷ 3 = 165 — 3 divides 495, so 495 is composite

    Nearest primes: 491 and 499
