So the greatest common factor 440,112,210 is 2.
Lets's calculate LCM of 247,729,499
Given numbers has no common factors except 1. So, there LCM is their product i.e 89851437
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/89851437
Therefore, the GCF of Fractions 440/247,112/729,210/499 is 2/89851437
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 247,729,499 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(247,729,499) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(247,729,499) x common factors =1 x 1 = 1
LCM(247,729,499) = ( 247 × 729 × 499 ) / 1
LCM(247,729,499) = 89851437 / 1
LCM(247,729,499) = 89851437
