Lets's calculate LCM of 131,2930
Given numbers has no common factors except 1. So, there LCM is their product i.e 383830
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 17/383830
Therefore, the GCF of Fractions 6171/131,1921/2930 is 17/383830
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 131,2930 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(131,2930) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(131,2930) x common factors =1 x 1 = 1
LCM(131,2930) = ( 131 × 2930 ) / 1
LCM(131,2930) = 383830 / 1
LCM(131,2930) = 383830
