So the greatest common factor 885,459 is 3.
Lets's calculate LCM of 723,643
Given numbers has no common factors except 1. So, there LCM is their product i.e 464889
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/464889
Therefore, the GCF of Fractions 885/723,459/643 is 3/464889
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 723,643 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(723,643) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(723,643) x common factors =1 x 1 = 1
LCM(723,643) = ( 723 × 643 ) / 1
LCM(723,643) = 464889 / 1
LCM(723,643) = 464889
