We found the factors 23,28 . The biggest common factor number is the GCF number.
So the greatest common factor 23,28 is 1.
Lets's calculate LCM of 787,5117
Given numbers has no common factors except 1. So, there LCM is their product i.e 4027079
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/4027079
Therefore, the GCF of Fractions 23/787,28/5117 is 1/4027079
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 787,5117 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(787,5117) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(787,5117) x common factors =1 x 1 = 1
LCM(787,5117) = ( 787 × 5117 ) / 1
LCM(787,5117) = 4027079 / 1
LCM(787,5117) = 4027079
