    Is 513 a prime or composite number?

    Answer

    Number 513 is not a Prime

    513 = 3³ × 19

    513 has 8 divisors — 1, 3, 9, 19, 27, 57, 171 and 513; a prime has exactly two: 1 and itself.

    Primes up to √513

    22² = 484 ≤ 513 < 529 = 23², so it is enough to try primes up to 22

    • ÷2 does not divide
    • ÷3 divides

    513 ÷ 3 = 171 — 3 divides 513, so 513 is composite

    Nearest primes: 509 and 521
