Lets's calculate LCM of 99,123
3 | 99, 123 |
33, 41 |
∴ So the LCM of the given numbers is 3 x 33 x 41 = 4059
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 17/4059
Therefore, the GCF of Fractions 289/99,918/123 is 17/4059
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 99,123 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(99,123) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(99,123) x common factors =3 x 1 = 3
LCM(99,123) = ( 99 × 123 ) / 3
LCM(99,123) = 12177 / 3
LCM(99,123) = 4059
