So the greatest common factor 18,10,279 is 1.
Lets's calculate LCM of 855,782,613
Given numbers has no common factors except 1. So, there LCM is their product i.e 409857930
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/409857930
Therefore, the GCF of Fractions 18/855,10/782,279/613 is 1/409857930
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 855,782,613 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(855,782,613) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(855,782,613) x common factors =1 x 1 = 1
LCM(855,782,613) = ( 855 × 782 × 613 ) / 1
LCM(855,782,613) = 409857930 / 1
LCM(855,782,613) = 409857930
