:1,5,23,115
Now, list down the factors of 279
:1,3,9,31,93,279
Greatest Common Factor
We found the factors 115,279 . The biggest common factor number is the GCF number.
So the greatest common factor 115,279 is 1.
Lets's calculate LCM of 810,389
Given numbers has no common factors except 1. So, there LCM is their product i.e 315090
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/315090
Therefore, the GCF of Fractions 115/810,279/389 is 1/315090
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 810,389 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(810,389) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(810,389) x common factors =1 x 1 = 1
LCM(810,389) = ( 810 × 389 ) / 1
LCM(810,389) = 315090 / 1
LCM(810,389) = 315090
