Lets's calculate LCM of 491,986
Given numbers has no common factors except 1. So, there LCM is their product i.e 484126
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 17/484126
Therefore, the GCF of Fractions 119/491,680/986 is 17/484126
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 491,986 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(491,986) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(491,986) x common factors =1 x 1 = 1
LCM(491,986) = ( 491 × 986 ) / 1
LCM(491,986) = 484126 / 1
LCM(491,986) = 484126
