Lets's calculate LCM of 616,883
Given numbers has no common factors except 1. So, there LCM is their product i.e 543928
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/543928
Therefore, the GCF of Fractions 642/616,508/883 is 2/543928
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 616,883 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(616,883) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(616,883) x common factors =1 x 1 = 1
LCM(616,883) = ( 616 × 883 ) / 1
LCM(616,883) = 543928 / 1
LCM(616,883) = 543928
