Greatest Common Factor
We found the factors 388,743 . The biggest common factor number is the GCF number.
So the greatest common factor 388,743 is 1.
Lets's calculate LCM of 264,487
Given numbers has no common factors except 1. So, there LCM is their product i.e 128568
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/128568
Therefore, the GCF of Fractions 388/264,743/487 is 1/128568
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 264,487 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(264,487) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(264,487) x common factors =1 x 1 = 1
LCM(264,487) = ( 264 × 487 ) / 1
LCM(264,487) = 128568 / 1
LCM(264,487) = 128568
