So the greatest common factor 543,861 is 3.
Lets's calculate LCM of 798,629
Given numbers has no common factors except 1. So, there LCM is their product i.e 501942
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/501942
Therefore, the GCF of Fractions 543/798,861/629 is 3/501942
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 798,629 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(798,629) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(798,629) x common factors =1 x 1 = 1
LCM(798,629) = ( 798 × 629 ) / 1
LCM(798,629) = 501942 / 1
LCM(798,629) = 501942
