So the greatest common factor 124,504 is 4.
Lets's calculate LCM of 809,991
Given numbers has no common factors except 1. So, there LCM is their product i.e 801719
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/801719
Therefore, the GCF of Fractions 124/809,504/991 is 4/801719
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 809,991 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(809,991) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(809,991) x common factors =1 x 1 = 1
LCM(809,991) = ( 809 × 991 ) / 1
LCM(809,991) = 801719 / 1
LCM(809,991) = 801719
