So the greatest common factor 957,399 is 3.
Lets's calculate LCM of 990,867
3 | 990, 867 |
330, 289 |
∴ So the LCM of the given numbers is 3 x 330 x 289 = 286110
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/286110
Therefore, the GCF of Fractions 957/990,399/867 is 3/286110
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 990,867 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(990,867) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(990,867) x common factors =3 x 1 = 3
LCM(990,867) = ( 990 × 867 ) / 3
LCM(990,867) = 858330 / 3
LCM(990,867) = 286110
