To find the least common denominator (LCD) of the fractions $\frac{1}{3}$, $\frac{5}{6}$, and $\frac{1}{6}$, we need to determine the least common multiple (LCM) of the denominators: 3 and 6.

The denominators are 3 and 6. The LCM of 3 and 6 is 6, since 6 is the smallest number divisible by both 3 and 6.

Thus, the least common denominator (LCD) of $\frac{1}{3}$, $\frac{5}{6}$, and $\frac{1}{6}$ is 6.
