Greatest Common Factor
We found the factors 487,623 . The biggest common factor number is the GCF number.
So the greatest common factor 487,623 is 1.
Lets's calculate LCM of 239,756
Given numbers has no common factors except 1. So, there LCM is their product i.e 180684
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/180684
Therefore, the GCF of Fractions 487/239,623/756 is 1/180684
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 239,756 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(239,756) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(239,756) x common factors =1 x 1 = 1
LCM(239,756) = ( 239 × 756 ) / 1
LCM(239,756) = 180684 / 1
LCM(239,756) = 180684
