Lets's calculate LCM of 77,3956
Given numbers has no common factors except 1. So, there LCM is their product i.e 304612
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/304612
Therefore, the GCF of Fractions 422/77,872/3956 is 2/304612
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 77,3956 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(77,3956) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(77,3956) x common factors =1 x 1 = 1
LCM(77,3956) = ( 77 × 3956 ) / 1
LCM(77,3956) = 304612 / 1
LCM(77,3956) = 304612
