    Is 74 a prime or composite number?

    Answer

    Number 74 is not a Prime

    74 = 2 × 37

    74 has 4 divisors — 1, 2, 37 and 74; a prime has exactly two: 1 and itself.

    Primes up to √74

    8² = 64 ≤ 74 < 81 = 9², so it is enough to try primes up to 8

    • ÷2 divides

    74 ÷ 2 = 37 — 2 divides 74, so 74 is composite

    Nearest primes: 73 and 79
