Is 741 a prime or composite number?

Answer

Number 741 is not a Prime

741 = 3 × 13 × 19

741 has 8 divisors — 1, 3, 13, 19, 39, 57, 247 and 741; a prime has exactly two: 1 and itself.

Primes up to √741

27² = 729 ≤ 741 < 784 = 28², so it is enough to try primes up to 27

÷2 does not divide
÷3 divides

741 ÷ 3 = 247 — 3 divides 741, so 741 is composite

Nearest primes: 739 and 743
