Find the Least Common Denominator (LCD) of the list of expressions: \(\frac{1}{x}, \frac{1}{x^2}, \frac{1}{x^3}\)

Step 1 ：The first step is to identify the denominators. They are \(x, x^2, x^3\).

Step 2 ：Next, we find the least common multiple (LCM) of the denominators. In this case, since they are all powers of the same base, the LCM is the highest power, which is \(x^3\).
