Is 963 a prime or composite number?

Answer

Number 963 is not a Prime

963 = 3² × 107

963 has 6 divisors — 1, 3, 9, 107, 321 and 963; a prime has exactly two: 1 and itself.

Primes up to √963

31² = 961 ≤ 963 < 1,024 = 32², so it is enough to try primes up to 31

  • ÷2 does not divide
  • ÷3 divides

963 ÷ 3 = 321 — 3 divides 963, so 963 is composite

Nearest primes: 953 and 967
