    Is 169 a prime or composite number?

    Answer

    Number 169 is not a Prime

    169 = 13²

    169 has 3 divisors — 1, 13 and 169; a prime has exactly two: 1 and itself. It is a perfect square.

    Primes up to √169

    13² = 169 ≤ 169 < 196 = 14², so it is enough to try primes up to 13

    • ÷2 does not divide
    • ÷3 does not divide
    • ÷5 does not divide
    • ÷7 does not divide
    • ÷11 does not divide
    • ÷13 divides

    169 ÷ 13 = 13 — 13 divides 169, so 169 is composite

    Nearest primes: 167 and 173
