Lets's calculate LCM of 793,1584
Given numbers has no common factors except 1. So, there LCM is their product i.e 1256112
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/1256112
Therefore, the GCF of Fractions 1638/793,3975/1584 is 3/1256112
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 793,1584 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(793,1584) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(793,1584) x common factors =1 x 1 = 1
LCM(793,1584) = ( 793 × 1584 ) / 1
LCM(793,1584) = 1256112 / 1
LCM(793,1584) = 1256112
