So the greatest common factor 441,390 is 3.
Lets's calculate LCM of 934,809
Given numbers has no common factors except 1. So, there LCM is their product i.e 755606
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/755606
Therefore, the GCF of Fractions 441/934,390/809 is 3/755606
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 934,809 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(934,809) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(934,809) x common factors =1 x 1 = 1
LCM(934,809) = ( 934 × 809 ) / 1
LCM(934,809) = 755606 / 1
LCM(934,809) = 755606
