    Is 711 a prime or composite number?

    Answer

    Number 711 is not a Prime

    711 = 3² × 79

    711 has 6 divisors — 1, 3, 9, 79, 237 and 711; a prime has exactly two: 1 and itself.

    Primes up to √711

    26² = 676 ≤ 711 < 729 = 27², so it is enough to try primes up to 26

    • ÷2 does not divide
    • ÷3 divides

    711 ÷ 3 = 237 — 3 divides 711, so 711 is composite

    Nearest primes: 709 and 719
