Lets's calculate LCM of 86,89,191
Given numbers has no common factors except 1. So, there LCM is their product i.e 1461914
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/1461914
Therefore, the GCF of Fractions 98/86,864/89,644/191 is 2/1461914
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 86,89,191 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(86,89,191) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(86,89,191) x common factors =1 x 1 = 1
LCM(86,89,191) = ( 86 × 89 × 191 ) / 1
LCM(86,89,191) = 1461914 / 1
LCM(86,89,191) = 1461914
