Lets's calculate LCM of 420,113
Given numbers has no common factors except 1. So, there LCM is their product i.e 47460
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/47460
Therefore, the GCF of Fractions 346/420,868/113 is 2/47460
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 420,113 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(420,113) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(420,113) x common factors =1 x 1 = 1
LCM(420,113) = ( 420 × 113 ) / 1
LCM(420,113) = 47460 / 1
LCM(420,113) = 47460
