Lets's calculate LCM of 489,718
Given numbers has no common factors except 1. So, there LCM is their product i.e 351102
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/351102
Therefore, the GCF of Fractions 255/489,222/718 is 3/351102
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 489,718 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(489,718) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(489,718) x common factors =1 x 1 = 1
LCM(489,718) = ( 489 × 718 ) / 1
LCM(489,718) = 351102 / 1
LCM(489,718) = 351102
