Is 901 a prime or composite number?

Answer

Number 901 is not a Prime

901 = 17 × 53

901 has 4 divisors — 1, 17, 53 and 901; a prime has exactly two: 1 and itself.

Primes up to √901

30² = 900 ≤ 901 < 961 = 31², so it is enough to try primes up to 30

  • ÷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

901 ÷ 17 = 53 — 17 divides 901, so 901 is composite

Nearest primes: 887 and 907
