Lets's calculate LCM of 17,958
Given numbers has no common factors except 1. So, there LCM is their product i.e 16286
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/16286
Therefore, the GCF of Fractions 494/17,420/958 is 2/16286
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 17,958 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(17,958) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(17,958) x common factors =1 x 1 = 1
LCM(17,958) = ( 17 × 958 ) / 1
LCM(17,958) = 16286 / 1
LCM(17,958) = 16286
