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
