So the greatest common factor 204,681 is 3.
Lets's calculate LCM of 391,163
Given numbers has no common factors except 1. So, there LCM is their product i.e 63733
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/63733
Therefore, the GCF of Fractions 204/391,681/163 is 3/63733
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 391,163 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(391,163) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(391,163) x common factors =1 x 1 = 1
LCM(391,163) = ( 391 × 163 ) / 1
LCM(391,163) = 63733 / 1
LCM(391,163) = 63733
