Greatest Common Factor
We found the factors 80,436,285 . The biggest common factor number is the GCF number.
So the greatest common factor 80,436,285 is 1.
Lets's calculate LCM of 40,73,719
Given numbers has no common factors except 1. So, there LCM is their product i.e 2099480
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/2099480
Therefore, the GCF of Fractions 80/40,436/73,285/719 is 1/2099480
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 40,73,719 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(40,73,719) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(40,73,719) x common factors =1 x 1 = 1
LCM(40,73,719) = ( 40 × 73 × 719 ) / 1
LCM(40,73,719) = 2099480 / 1
LCM(40,73,719) = 2099480
