So the greatest common factor 15,15,255 is 15.
Lets's calculate LCM of 287,103,747
Given numbers has no common factors except 1. So, there LCM is their product i.e 22082067
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 15/22082067
Therefore, the GCF of Fractions 15/287,15/103,255/747 is 15/22082067
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 287,103,747 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(287,103,747) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(287,103,747) x common factors =1 x 1 = 1
LCM(287,103,747) = ( 287 × 103 × 747 ) / 1
LCM(287,103,747) = 22082067 / 1
LCM(287,103,747) = 22082067
