    Is 49 a prime or composite number?

    Answer

    Number 49 is not a Prime

    49 = 7²

    49 has 3 divisors — 1, 7 and 49; a prime has exactly two: 1 and itself. It is a perfect square.

    Primes up to √49

    7² = 49 ≤ 49 < 64 = 8², so it is enough to try primes up to 7

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

    49 ÷ 7 = 7 — 7 divides 49, so 49 is composite

    Nearest primes: 47 and 53
