Is 473 a prime or composite number?

Answer

Number 473 is not a Prime

473 = 11 × 43

473 has 4 divisors — 1, 11, 43 and 473; a prime has exactly two: 1 and itself.

Primes up to √473

21² = 441 ≤ 473 < 484 = 22², so it is enough to try primes up to 21

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

473 ÷ 11 = 43 — 11 divides 473, so 473 is composite

Nearest primes: 467 and 479
