    Is 539 a prime or composite number?

    Answer

    Number 539 is not a Prime

    539 = 7² × 11

    539 has 6 divisors — 1, 7, 11, 49, 77 and 539; a prime has exactly two: 1 and itself.

    Primes up to √539

    23² = 529 ≤ 539 < 576 = 24², so it is enough to try primes up to 23

    • ÷2 does not divide
    • ÷3 does not divide
    • ÷5 does not divide
    • ÷7 divides

    539 ÷ 7 = 77 — 7 divides 539, so 539 is composite

    Nearest primes: 523 and 541
