So the greatest common factor 398,132 is 2.
Lets's calculate LCM of 809,204
Given numbers has no common factors except 1. So, there LCM is their product i.e 165036
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/165036
Therefore, the GCF of Fractions 398/809,132/204 is 2/165036
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 809,204 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(809,204) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(809,204) x common factors =1 x 1 = 1
LCM(809,204) = ( 809 × 204 ) / 1
LCM(809,204) = 165036 / 1
LCM(809,204) = 165036
