    Is 679 a prime or composite number?

    Answer

    Number 679 is not a Prime

    679 = 7 × 97

    679 has 4 divisors — 1, 7, 97 and 679; a prime has exactly two: 1 and itself.

    Primes up to √679

    26² = 676 ≤ 679 < 729 = 27², so it is enough to try primes up to 26

    • ÷2 does not divide
    • ÷3 does not divide
    • ÷5 does not divide
    • ÷7 divides

    679 ÷ 7 = 97 — 7 divides 679, so 679 is composite

    Nearest primes: 677 and 683
