So the greatest common factor 80,3172 is 4.
Lets's calculate LCM of 986,6317
Given numbers has no common factors except 1. So, there LCM is their product i.e 6228562
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/6228562
Therefore, the GCF of Fractions 80/986,3172/6317 is 4/6228562
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 986,6317 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(986,6317) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(986,6317) x common factors =1 x 1 = 1
LCM(986,6317) = ( 986 × 6317 ) / 1
LCM(986,6317) = 6228562 / 1
LCM(986,6317) = 6228562
