    What is the Greatest Common Divisor of 13 and 22?

    Answer

    GCF (HCF) of 13 and 22 is
    1

    Common factors: 1

    Only 1 divides both: 13 and 22 share no prime factor.

    Such numbers are called coprime (relatively prime); their LCM is just the product: 13 × 22 = 286.

    13 — prime

    22 = 2 × 11
