Greatest Common Factor
We found the factors 285,570,396 . The biggest common factor number is the GCF number.
So the greatest common factor 285,570,396 is 3.
Lets's calculate LCM of 35,97,389
Given numbers has no common factors except 1. So, there LCM is their product i.e 1320655
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/1320655
Therefore, the GCF of Fractions 285/35,570/97,396/389 is 3/1320655
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 35,97,389 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(35,97,389) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(35,97,389) x common factors =1 x 1 = 1
LCM(35,97,389) = ( 35 × 97 × 389 ) / 1
LCM(35,97,389) = 1320655 / 1
LCM(35,97,389) = 1320655
