Lets's calculate LCM of 396,989
Given numbers has no common factors except 1. So, there LCM is their product i.e 391644
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/391644
Therefore, the GCF of Fractions 406/396,456/989 is 2/391644
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 396,989 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(396,989) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(396,989) x common factors =1 x 1 = 1
LCM(396,989) = ( 396 × 989 ) / 1
LCM(396,989) = 391644 / 1
LCM(396,989) = 391644
