    Is 48 a prime or composite number?

    Answer

    Number 48 is not a Prime

    48 = 2⁴ × 3

    48 has 10 divisors, not two: a prime is divisible only by 1 and itself.

    Primes up to √48

    6² = 36 ≤ 48 < 49 = 7², so it is enough to try primes up to 6

    • ÷2 divides

    48 ÷ 2 = 24 — 2 divides 48, so 48 is composite

    Nearest primes: 47 and 53
