    Is 102 a prime or composite number?

    Answer

    Number 102 is not a Prime

    102 = 2 × 3 × 17

    102 has 8 divisors — 1, 2, 3, 6, 17, 34, 51 and 102; a prime has exactly two: 1 and itself.

    Primes up to √102

    10² = 100 ≤ 102 < 121 = 11², so it is enough to try primes up to 10

    • ÷2 divides

    102 ÷ 2 = 51 — 2 divides 102, so 102 is composite

    Nearest primes: 101 and 103
