The least common denominator (LCD) must account for all factors present in the denominators of the fractions, with the highest power for any repeated factors. Here, the denominators are $3a^2$ and $a^3$. The LCD must include the factor of 3 and $a$ raised to the highest power seen, which is $a^3$. Thus, the LCD is $3a^3$.
