Is 955 a prime or composite number?

Answer

Number 955 is not a Prime

955 = 5 × 191

955 has 4 divisors — 1, 5, 191 and 955; a prime has exactly two: 1 and itself.

Primes up to √955

30² = 900 ≤ 955 < 961 = 31², so it is enough to try primes up to 30

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

955 ÷ 5 = 191 — 5 divides 955, so 955 is composite

Nearest primes: 953 and 967
