    What is the Greatest Common Divisor of 44 and 45?

    Answer

    GCF (HCF) of 44 and 45 is
    1

    Common factors: 1

    Only 1 divides both: 44 and 45 share no prime factor.

    Such numbers are called coprime (relatively prime); their LCM is just the product: 44 × 45 = 1,980.

    44 = 22 × 11

    45 = 32 × 5

    — = power 0: the prime is not a factor of this number, so it cannot be in the GCF.

    GCF = 1
