Is 363 a prime or composite number?

Answer

Number 363 is not a Prime

363 = 3 × 11²

363 has 6 divisors — 1, 3, 11, 33, 121 and 363; a prime has exactly two: 1 and itself.

Primes up to √363

19² = 361 ≤ 363 < 400 = 20², so it is enough to try primes up to 19

  • ÷2 does not divide
  • ÷3 divides

363 ÷ 3 = 121 — 3 divides 363, so 363 is composite
