So the greatest common factor 1990,6831 is 1.
Lets's calculate LCM of 473,9898
Given numbers has no common factors except 1. So, there LCM is their product i.e 4681754
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/4681754
Therefore, the GCF of Fractions 1990/473,6831/9898 is 1/4681754
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 473,9898 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(473,9898) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(473,9898) x common factors =1 x 1 = 1
LCM(473,9898) = ( 473 × 9898 ) / 1
LCM(473,9898) = 4681754 / 1
LCM(473,9898) = 4681754
