Lets's calculate LCM of 815,656
Given numbers has no common factors except 1. So, there LCM is their product i.e 534640
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 78/534640
Therefore, the GCF of Fractions 546/815,624/656 is 78/534640
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 815,656 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(815,656) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(815,656) x common factors =1 x 1 = 1
LCM(815,656) = ( 815 × 656 ) / 1
LCM(815,656) = 534640 / 1
LCM(815,656) = 534640
