    Is 2,019 a prime or composite number?

    Answer

    Number 2,019 is not a Prime

    2,019 = 3 × 673

    2,019 has 4 divisors — 1, 3, 673 and 2,019; a prime has exactly two: 1 and itself.

    Primes up to √2,019

    44² = 1,936 ≤ 2,019 < 2,025 = 45², so it is enough to try primes up to 44

    • ÷2 does not divide
    • ÷3 divides

    2,019 ÷ 3 = 673 — 3 divides 2,019, so 2,019 is composite

    Nearest primes: 2,017 and 2,027
