Greatest Common Factor
We found the factors 388,8404 . The biggest common factor number is the GCF number.
So the greatest common factor 388,8404 is 4.
Lets's calculate LCM of 151,191
Given numbers has no common factors except 1. So, there LCM is their product i.e 28841
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/28841
Therefore, the GCF of Fractions 388/151,8404/191 is 4/28841
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 151,191 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(151,191) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(151,191) x common factors =1 x 1 = 1
LCM(151,191) = ( 151 × 191 ) / 1
LCM(151,191) = 28841 / 1
LCM(151,191) = 28841
