Lets's calculate LCM of 317,179,924
Given numbers has no common factors except 1. So, there LCM is their product i.e 52430532
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/52430532
Therefore, the GCF of Fractions 15/317,420/179,546/924 is 3/52430532
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 317,179,924 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(317,179,924) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(317,179,924) x common factors =1 x 1 = 1
LCM(317,179,924) = ( 317 × 179 × 924 ) / 1
LCM(317,179,924) = 52430532 / 1
LCM(317,179,924) = 52430532
