Lets's calculate LCM of 655,517
Given numbers has no common factors except 1. So, there LCM is their product i.e 338635
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/338635
Therefore, the GCF of Fractions 868/655,618/517 is 2/338635
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 655,517 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(655,517) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(655,517) x common factors =1 x 1 = 1
LCM(655,517) = ( 655 × 517 ) / 1
LCM(655,517) = 338635 / 1
LCM(655,517) = 338635
