Lets's calculate GCF of 386,990
2 | 386, 990 |
193, 495 |
∴ So the GCF of the given numbers is 2 = 2
Now, list down the factors of 386
:1,2,193,386
Now, list down the factors of 990
: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 386,990 . The biggest common factor number is the GCF number.
So the greatest common factor 386,990 is 2.
Lets's calculate LCM of 195,191
Given numbers has no common factors except 1. So, there LCM is their product i.e 37245
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/37245
Therefore, the GCF of Fractions 386/195,990/191 is 2/37245
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 195,191 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(195,191) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(195,191) x common factors =1 x 1 = 1
LCM(195,191) = ( 195 × 191 ) / 1
LCM(195,191) = 37245 / 1
LCM(195,191) = 37245
