So the greatest common factor 676,408 is 4.
Lets's calculate LCM of 469,873
Given numbers has no common factors except 1. So, there LCM is their product i.e 409437
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/409437
Therefore, the GCF of Fractions 676/469,408/873 is 4/409437
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 469,873 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(469,873) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(469,873) x common factors =1 x 1 = 1
LCM(469,873) = ( 469 × 873 ) / 1
LCM(469,873) = 409437 / 1
LCM(469,873) = 409437
