    Is 388 a prime or composite number?

    Answer

    Number 388 is not a Prime

    388 = 2² × 97

    388 has 6 divisors — 1, 2, 4, 97, 194 and 388; a prime has exactly two: 1 and itself.

    Primes up to √388

    19² = 361 ≤ 388 < 400 = 20², so it is enough to try primes up to 19

    • ÷2 divides

    388 ÷ 2 = 194 — 2 divides 388, so 388 is composite

    Nearest primes: 383 and 389
