Lets's calculate LCM of 957,584
Given numbers has no common factors except 1. So, there LCM is their product i.e 558888
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/558888
Therefore, the GCF of Fractions 398/957,436/584 is 2/558888
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 957,584 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(957,584) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(957,584) x common factors =1 x 1 = 1
LCM(957,584) = ( 957 × 584 ) / 1
LCM(957,584) = 558888 / 1
LCM(957,584) = 558888
