Lets's calculate LCM of 646,7433
Given numbers has no common factors except 1. So, there LCM is their product i.e 4801718
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 9/4801718
Therefore, the GCF of Fractions 1143/646,2799/7433 is 9/4801718
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 646,7433 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(646,7433) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(646,7433) x common factors =1 x 1 = 1
LCM(646,7433) = ( 646 × 7433 ) / 1
LCM(646,7433) = 4801718 / 1
LCM(646,7433) = 4801718
