1,3,2213,6639
Greatest Common Factor
We found the factors 605,6639 . The biggest common factor number is the GCF number.
So the greatest common factor 605,6639 is 1.
Lets's calculate LCM of 198,198
2 | 198, 198 |
3 | 99, 99 |
3 | 33, 33 |
11 | 11, 11 |
1, 1 |
∴ So the LCM of the given numbers is 2 x 3 x 3 x 11 x 1 x 1 = 198
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/198
Therefore, the GCF of Fractions 605/198,6639/198 is 1/198
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 198,198 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(198,198) = 198
common factors(in case of two or more numbers have common factors) = 1
GCF(198,198) x common factors =198 x 1 = 198
LCM(198,198) = ( 198 × 198 ) / 198
LCM(198,198) = 39204 / 198
LCM(198,198) = 198
