Greatest Common Factor
We found the factors 712,519 . The biggest common factor number is the GCF number.
So the greatest common factor 712,519 is 1.
Lets's calculate LCM of 785,317
Given numbers has no common factors except 1. So, there LCM is their product i.e 248845
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/248845
Therefore, the GCF of Fractions 712/785,519/317 is 1/248845
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 785,317 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(785,317) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(785,317) x common factors =1 x 1 = 1
LCM(785,317) = ( 785 × 317 ) / 1
LCM(785,317) = 248845 / 1
LCM(785,317) = 248845
