Lets's calculate LCM of 686,3425
Given numbers has no common factors except 1. So, there LCM is their product i.e 2349550
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/2349550
Therefore, the GCF of Fractions 6561/686,8688/3425 is 3/2349550
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 686,3425 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(686,3425) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(686,3425) x common factors =1 x 1 = 1
LCM(686,3425) = ( 686 × 3425 ) / 1
LCM(686,3425) = 2349550 / 1
LCM(686,3425) = 2349550
