So the greatest common factor 693,642 is 3.
Lets's calculate LCM of 718,597
Given numbers has no common factors except 1. So, there LCM is their product i.e 428646
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/428646
Therefore, the GCF of Fractions 693/718,642/597 is 3/428646
The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).
We need to calculate greatest common factor of 718,597 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(718,597) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(718,597) x common factors =1 x 1 = 1
LCM(718,597) = ( 718 × 597 ) / 1
LCM(718,597) = 428646 / 1
LCM(718,597) = 428646
