Is 471 a prime or composite number?

Answer

Number 471 is not a Prime

471 = 3 × 157

471 has 4 divisors — 1, 3, 157 and 471; a prime has exactly two: 1 and itself.

Primes up to √471

21² = 441 ≤ 471 < 484 = 22², so it is enough to try primes up to 21

  • ÷2 does not divide
  • ÷3 divides

471 ÷ 3 = 157 — 3 divides 471, so 471 is composite

Nearest primes: 467 and 479
