Lets's calculate LCM of 280,8327
Given numbers has no common factors except 1. So, there LCM is their product i.e 2331560
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/2331560
Therefore, the GCF of Fractions 621/280,4398/8327 is 3/2331560
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 280,8327 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(280,8327) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(280,8327) x common factors =1 x 1 = 1
LCM(280,8327) = ( 280 × 8327 ) / 1
LCM(280,8327) = 2331560 / 1
LCM(280,8327) = 2331560
