Lets's calculate LCM of 284,727
Given numbers has no common factors except 1. So, there LCM is their product i.e 206468
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/206468
Therefore, the GCF of Fractions 686/284,954/727 is 2/206468
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 284,727 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(284,727) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(284,727) x common factors =1 x 1 = 1
LCM(284,727) = ( 284 × 727 ) / 1
LCM(284,727) = 206468 / 1
LCM(284,727) = 206468
