Greatest Common Factor
We found the factors 405,591 . The biggest common factor number is the GCF number.
So the greatest common factor 405,591 is 3.
Lets's calculate LCM of 174,835
Given numbers has no common factors except 1. So, there LCM is their product i.e 145290
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/145290
Therefore, the GCF of Fractions 405/174,591/835 is 3/145290
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 174,835 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(174,835) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(174,835) x common factors =1 x 1 = 1
LCM(174,835) = ( 174 × 835 ) / 1
LCM(174,835) = 145290 / 1
LCM(174,835) = 145290
