So the greatest common factor 315,957 is 3.
Lets's calculate LCM of 403,836
Given numbers has no common factors except 1. So, there LCM is their product i.e 336908
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/336908
Therefore, the GCF of Fractions 315/403,957/836 is 3/336908
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 403,836 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(403,836) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(403,836) x common factors =1 x 1 = 1
LCM(403,836) = ( 403 × 836 ) / 1
LCM(403,836) = 336908 / 1
LCM(403,836) = 336908
