Lets's calculate LCM of 18,48,82,328
| 2 | 18, 48, 82, 328 |
| 2 | 9, 24, 41, 164 |
| 2 | 9, 12, 41, 82 |
| 3 | 9, 6, 41, 41 |
| 41 | 3, 2, 41, 41 |
| 3, 2, 1, 1 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 3 x 41 x 3 x 2 x 1 x 1 = 5904
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/5904

Least Common Multiple of 18,48,82,328 with GCF Formula
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 18,48,82,328 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(18,48,82,328) = 2
common factors(in case of two or more numbers have common factors) = 1968
GCF(18,48,82,328) x common factors =2 x 1968 = 3936
LCM(18,48,82,328) = ( 18 × 48 × 82 × 328 ) / 3936
LCM(18,48,82,328) = 23238144 / 3936
LCM(18,48,82,328) = 5904
