    Is 252 a prime or composite number?

    Answer

    Number 252 is not a Prime

    252 = 2² × 3² × 7

    252 has 18 divisors, not two: a prime is divisible only by 1 and itself.

    Primes up to √252

    15² = 225 ≤ 252 < 256 = 16², so it is enough to try primes up to 15

    • ÷2 divides

    252 ÷ 2 = 126 — 2 divides 252, so 252 is composite

    Nearest primes: 251 and 257
