The objective is to find the fact families for the set of numbers 3, 6, 18.

The fact familes is defined as the set of four operations related to the given 3 numbers.

Thus, the fact families are,

`\begin{gathered} 3*6=18 \\ 6*3=18 \\ 18\text{ / 3=6} \\ 18\text{ / 6 =3} \end{gathered}`

Hence, the required fact families is obtained.
