    Is 738 a prime or composite number?

    Answer

    Number 738 is not a Prime

    738 = 2 × 3² × 41

    738 has 12 divisors, not two: a prime is divisible only by 1 and itself.

    Primes up to √738

    27² = 729 ≤ 738 < 784 = 28², so it is enough to try primes up to 27

    • ÷2 divides

    738 ÷ 2 = 369 — 2 divides 738, so 738 is composite

    Nearest primes: 733 and 739
