Lets's calculate LCM of 421,478
Given numbers has no common factors except 1. So, there LCM is their product i.e 201238
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/201238
Therefore, the GCF of Fractions 2788/421,7376/478 is 4/201238
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 421,478 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(421,478) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(421,478) x common factors =1 x 1 = 1
LCM(421,478) = ( 421 × 478 ) / 1
LCM(421,478) = 201238 / 1
LCM(421,478) = 201238
