So the greatest common factor 378,557 is 1.
Lets's calculate LCM of 406,891
Given numbers has no common factors except 1. So, there LCM is their product i.e 361746
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/361746
Therefore, the GCF of Fractions 378/406,557/891 is 1/361746
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 406,891 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(406,891) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(406,891) x common factors =1 x 1 = 1
LCM(406,891) = ( 406 × 891 ) / 1
LCM(406,891) = 361746 / 1
LCM(406,891) = 361746
