Lets's calculate LCM of 408,989
Given numbers has no common factors except 1. So, there LCM is their product i.e 403512
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/403512
Therefore, the GCF of Fractions 896/408,158/989 is 2/403512
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 408,989 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(408,989) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(408,989) x common factors =1 x 1 = 1
LCM(408,989) = ( 408 × 989 ) / 1
LCM(408,989) = 403512 / 1
LCM(408,989) = 403512
