1,2,3,5,6,9,10,11,15,18,22,30,33,45,55,66,90,99,110,165,198,330,495,990
Greatest Common Factor
We found the factors 78,61,990 . The biggest common factor number is the GCF number.
So the greatest common factor 78,61,990 is 1.
Lets's calculate LCM of 617,230,981
Given numbers has no common factors except 1. So, there LCM is their product i.e 139213710
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/139213710
Therefore, the GCF of Fractions 78/617,61/230,990/981 is 1/139213710
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 617,230,981 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(617,230,981) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(617,230,981) x common factors =1 x 1 = 1
LCM(617,230,981) = ( 617 × 230 × 981 ) / 1
LCM(617,230,981) = 139213710 / 1
LCM(617,230,981) = 139213710
