Is 940 a prime or composite number?

Answer

Number 940 is not a Prime

940 = 2² × 5 × 47

940 has 12 divisors, not two: a prime is divisible only by 1 and itself.

Primes up to √940

30² = 900 ≤ 940 < 961 = 31², so it is enough to try primes up to 30

  • ÷2 divides

940 ÷ 2 = 470 — 2 divides 940, so 940 is composite

Nearest primes: 937 and 941
