Is 1,175 a prime or composite number?

Answer

Number 1,175 is not a Prime

1,175 = 5² × 47

1,175 has 6 divisors — 1, 5, 25, 47, 235 and 1,175; a prime has exactly two: 1 and itself.

Primes up to √1,175

34² = 1,156 ≤ 1,175 < 1,225 = 35², so it is enough to try primes up to 34

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

1,175 ÷ 5 = 235 — 5 divides 1,175, so 1,175 is composite

Nearest primes: 1,171 and 1,181
