Lets's calculate LCM of 457,191
Given numbers has no common factors except 1. So, there LCM is their product i.e 87287
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/87287
Therefore, the GCF of Fractions 797/457,768/191 is 1/87287
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 457,191 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(457,191) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(457,191) x common factors =1 x 1 = 1
LCM(457,191) = ( 457 × 191 ) / 1
LCM(457,191) = 87287 / 1
LCM(457,191) = 87287
