    Is 183 a prime or composite number?

    Answer

    Number 183 is not a Prime

    183 = 3 × 61

    183 has 4 divisors — 1, 3, 61 and 183; a prime has exactly two: 1 and itself.

    Primes up to √183

    13² = 169 ≤ 183 < 196 = 14², so it is enough to try primes up to 13

    • ÷2 does not divide
    • ÷3 divides

    183 ÷ 3 = 61 — 3 divides 183, so 183 is composite

    Nearest primes: 181 and 191
