Lets's calculate LCM of 171,439,818
Given numbers has no common factors except 1. So, there LCM is their product i.e 61406442
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/61406442
Therefore, the GCF of Fractions 20/171,954/439,728/818 is 2/61406442
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 171,439,818 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(171,439,818) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(171,439,818) x common factors =1 x 1 = 1
LCM(171,439,818) = ( 171 × 439 × 818 ) / 1
LCM(171,439,818) = 61406442 / 1
LCM(171,439,818) = 61406442
