Lets's calculate LCM of 9197,4761
Given numbers has no common factors except 1. So, there LCM is their product i.e 43786917
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/43786917
Therefore, the GCF of Fractions 638/9197,138/4761 is 2/43786917
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 9197,4761 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(9197,4761) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(9197,4761) x common factors =1 x 1 = 1
LCM(9197,4761) = ( 9197 × 4761 ) / 1
LCM(9197,4761) = 43786917 / 1
LCM(9197,4761) = 43786917
