1,3,2423,7269
Greatest Common Factor
We found the factors 4080,7269 . The biggest common factor number is the GCF number.
So the greatest common factor 4080,7269 is 3.
Lets's calculate LCM of 512,655
Given numbers has no common factors except 1. So, there LCM is their product i.e 335360
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/335360
Therefore, the GCF of Fractions 4080/512,7269/655 is 3/335360
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 512,655 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(512,655) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(512,655) x common factors =1 x 1 = 1
LCM(512,655) = ( 512 × 655 ) / 1
LCM(512,655) = 335360 / 1
LCM(512,655) = 335360
Here are some samples of GCF of Fractions calculations.
