So the greatest common factor 477,870 is 3.
Lets's calculate LCM of 311,388
Given numbers has no common factors except 1. So, there LCM is their product i.e 120668
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/120668
Therefore, the GCF of Fractions 477/311,870/388 is 3/120668
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 311,388 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(311,388) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(311,388) x common factors =1 x 1 = 1
LCM(311,388) = ( 311 × 388 ) / 1
LCM(311,388) = 120668 / 1
LCM(311,388) = 120668
