527 = 17 × 31

527 has 4 divisors — 1, 17, 31 and 527; a prime has exactly two: 1 and itself.

Primes up to √527

22² = 484 ≤ 527 < 529 = 23², so it is enough to try primes up to 22

  • ÷2 does not divide
  • ÷3 does not divide
  • ÷5 does not divide
  • ÷7 does not divide
  • ÷11 does not divide
  • ÷13 does not divide
  • ÷17 divides

527 ÷ 17 = 31 — 17 divides 527, so 527 is composite

Nearest primes: 523 and 541
