So the greatest common factor 450,128 is 2.
Lets's calculate LCM of 638,983
Given numbers has no common factors except 1. So, there LCM is their product i.e 627154
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/627154
Therefore, the GCF of Fractions 450/638,128/983 is 2/627154
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 638,983 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(638,983) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(638,983) x common factors =1 x 1 = 1
LCM(638,983) = ( 638 × 983 ) / 1
LCM(638,983) = 627154 / 1
LCM(638,983) = 627154
