Is 801 a prime or composite number?

Answer

Number 801 is not a Prime

801 = 3² × 89

801 has 6 divisors — 1, 3, 9, 89, 267 and 801; a prime has exactly two: 1 and itself.

Primes up to √801

28² = 784 ≤ 801 < 841 = 29², so it is enough to try primes up to 28

  • ÷2 does not divide
  • ÷3 divides

801 ÷ 3 = 267 — 3 divides 801, so 801 is composite

Nearest primes: 797 and 809
