    Is 377 a prime or composite number?

    Answer

    Number 377 is not a Prime

    377 = 13 × 29

    377 has 4 divisors — 1, 13, 29 and 377; a prime has exactly two: 1 and itself.

    Primes up to √377

    19² = 361 ≤ 377 < 400 = 20², so it is enough to try primes up to 19

    • ÷2 does not divide
    • ÷3 does not divide
    • ÷5 does not divide
    • ÷7 does not divide
    • ÷11 does not divide
    • ÷13 divides

    377 ÷ 13 = 29 — 13 divides 377, so 377 is composite

    Nearest primes: 373 and 379
