Lets's calculate LCM of 885,389
Given numbers has no common factors except 1. So, there LCM is their product i.e 344265
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/344265
Therefore, the GCF of Fractions 424/885,398/389 is 2/344265
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 885,389 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(885,389) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(885,389) x common factors =1 x 1 = 1
LCM(885,389) = ( 885 × 389 ) / 1
LCM(885,389) = 344265 / 1
LCM(885,389) = 344265
