    Is 1,331 a prime or composite number?

    Answer

    Number 1,331 is not a Prime

    1,331 = 11³

    1,331 has 4 divisors — 1, 11, 121 and 1,331; a prime has exactly two: 1 and itself.

    Primes up to √1,331

    36² = 1,296 ≤ 1,331 < 1,369 = 37², so it is enough to try primes up to 36

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

    1,331 ÷ 11 = 121 — 11 divides 1,331, so 1,331 is composite

    Nearest primes: 1,327 and 1,361
