So the greatest common factor 912,728 is 8.
Lets's calculate LCM of 472,831
Given numbers has no common factors except 1. So, there LCM is their product i.e 392232
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 8/392232
Therefore, the GCF of Fractions 912/472,728/831 is 8/392232
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 472,831 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(472,831) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(472,831) x common factors =1 x 1 = 1
LCM(472,831) = ( 472 × 831 ) / 1
LCM(472,831) = 392232 / 1
LCM(472,831) = 392232
