    Is 432 a prime or composite number?

    Answer

    Number 432 is not a Prime

    432 = 2⁴ × 3³

    432 has 20 divisors, not two: a prime is divisible only by 1 and itself.

    Primes up to √432

    20² = 400 ≤ 432 < 441 = 21², so it is enough to try primes up to 20

    • ÷2 divides

    432 ÷ 2 = 216 — 2 divides 432, so 432 is composite

    Nearest primes: 431 and 433
