So the greatest common factor 18,749,278 is 1.
Lets's calculate LCM of 30,99,369
3 | 30, 99, 369 |
3 | 10, 33, 123 |
10, 11, 41 |
∴ So the LCM of the given numbers is 3 x 3 x 10 x 11 x 41 = 40590
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/40590
Therefore, the GCF of Fractions 18/30,749/99,278/369 is 1/40590
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 30,99,369 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(30,99,369) = 3
common factors(in case of two or more numbers have common factors) = 9
GCF(30,99,369) x common factors =3 x 9 = 27
LCM(30,99,369) = ( 30 × 99 × 369 ) / 27
LCM(30,99,369) = 1095930 / 27
LCM(30,99,369) = 40590
