Lets's calculate LCM of 378,913
Given numbers has no common factors except 1. So, there LCM is their product i.e 345114
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 10/345114
Therefore, the GCF of Fractions 860/378,690/913 is 10/345114
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 378,913 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(378,913) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(378,913) x common factors =1 x 1 = 1
LCM(378,913) = ( 378 × 913 ) / 1
LCM(378,913) = 345114 / 1
LCM(378,913) = 345114
