Greatest Common Factor
We found the factors 80,561,115 . The biggest common factor number is the GCF number.
So the greatest common factor 80,561,115 is 1.
Lets's calculate LCM of 29,91,804
Given numbers has no common factors except 1. So, there LCM is their product i.e 2121756
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/2121756
Therefore, the GCF of Fractions 80/29,561/91,115/804 is 1/2121756
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 29,91,804 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(29,91,804) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(29,91,804) x common factors =1 x 1 = 1
LCM(29,91,804) = ( 29 × 91 × 804 ) / 1
LCM(29,91,804) = 2121756 / 1
LCM(29,91,804) = 2121756
