    Is 1,241 a prime or composite number?

    Answer

    Number 1,241 is not a Prime

    1,241 = 17 × 73

    1,241 has 4 divisors — 1, 17, 73 and 1,241; a prime has exactly two: 1 and itself.

    Primes up to √1,241

    35² = 1,225 ≤ 1,241 < 1,296 = 36², so it is enough to try primes up to 35

    • ÷2 does not divide
    • ÷3 does not divide
    • ÷5 does not divide
    • ÷7 does not divide
    • ÷11 does not divide
    • ÷13 does not divide
    • ÷17 divides

    1,241 ÷ 17 = 73 — 17 divides 1,241, so 1,241 is composite

    Nearest primes: 1,237 and 1,249
