So the greatest common factor 338,620 is 2.
Lets's calculate LCM of 391,836
Given numbers has no common factors except 1. So, there LCM is their product i.e 326876
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/326876
Therefore, the GCF of Fractions 338/391,620/836 is 2/326876
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 391,836 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(391,836) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(391,836) x common factors =1 x 1 = 1
LCM(391,836) = ( 391 × 836 ) / 1
LCM(391,836) = 326876 / 1
LCM(391,836) = 326876
