    Is 2,015 a prime or composite number?

    Answer

    Number 2,015 is not a Prime

    2,015 = 5 × 13 × 31

    2,015 has 8 divisors — 1, 5, 13, 31, 65, 155, 403 and 2,015; a prime has exactly two: 1 and itself.

    Primes up to √2,015

    44² = 1,936 ≤ 2,015 < 2,025 = 45², so it is enough to try primes up to 44

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

    2,015 ÷ 5 = 403 — 5 divides 2,015, so 2,015 is composite

    Nearest primes: 2,011 and 2,017
