So the greatest common factor 396,1372 is 4.
Lets's calculate LCM of 397,982
Given numbers has no common factors except 1. So, there LCM is their product i.e 389854
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/389854
Therefore, the GCF of Fractions 396/397,1372/982 is 4/389854
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 397,982 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(397,982) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(397,982) x common factors =1 x 1 = 1
LCM(397,982) = ( 397 × 982 ) / 1
LCM(397,982) = 389854 / 1
LCM(397,982) = 389854
