Lets's calculate LCM of 583,887
Given numbers has no common factors except 1. So, there LCM is their product i.e 517121
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/517121
Therefore, the GCF of Fractions 496/583,420/887 is 4/517121
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 583,887 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(583,887) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(583,887) x common factors =1 x 1 = 1
LCM(583,887) = ( 583 × 887 ) / 1
LCM(583,887) = 517121 / 1
LCM(583,887) = 517121
