So the greatest common factor 270,117 is 9.
Lets's calculate LCM of 809,615
Given numbers has no common factors except 1. So, there LCM is their product i.e 497535
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 9/497535
Therefore, the GCF of Fractions 270/809,117/615 is 9/497535
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 809,615 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(809,615) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(809,615) x common factors =1 x 1 = 1
LCM(809,615) = ( 809 × 615 ) / 1
LCM(809,615) = 497535 / 1
LCM(809,615) = 497535
