So the greatest common factor 18,698,922 is 2.
Lets's calculate LCM of 397,927,999
3 | 397, 927, 999 |
3 | 397, 309, 333 |
397, 103, 111 |
∴ So the LCM of the given numbers is 3 x 3 x 397 x 103 x 111 = 40850109
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/40850109
Therefore, the GCF of Fractions 18/397,698/927,922/999 is 2/40850109
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 397,927,999 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(397,927,999) = 1
common factors(in case of two or more numbers have common factors) = 9
GCF(397,927,999) x common factors =1 x 9 = 9
LCM(397,927,999) = ( 397 × 927 × 999 ) / 9
LCM(397,927,999) = 367650981 / 9
LCM(397,927,999) = 40850109
