Lets's calculate LCM of 991,259
Given numbers has no common factors except 1. So, there LCM is their product i.e 256669
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 9/256669
Therefore, the GCF of Fractions 2205/991,9117/259 is 9/256669
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 991,259 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(991,259) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(991,259) x common factors =1 x 1 = 1
LCM(991,259) = ( 991 × 259 ) / 1
LCM(991,259) = 256669 / 1
LCM(991,259) = 256669
