This problem is confusing me a little, specifically the "x|y."

Would this be correct? The loops around the numbers signify a relation.

Hello, Don!

Do you understand that $\displaystyle x|y$ means "$\displaystyle x\text{ divides }y$" ?

Since every number divides itself, your diagram is correct . . . so far.

But you missed a few others . . .

. . 2 divides 4, 2 divides 6, 2 divides 8.

. . 3 divides 6.

. . 4 divides 8.

You should have arrows indicating those pairs, too:

.$\displaystyle \begin{array}{ccc}& & 4 \\ & \nearrow & \\ 2 & \rightarrow & 6 \\ & \searrow & \\ & & 8 \end{array}\qquad \text{and }\;3\to6\qquad \text{and }\;4\to8$

We should have Latex art competitions.

Yeah, creative :)

I made it with MathType. (Which really takes less time.)

The following code is required:

\begin{array}{*{20}c}

{} & {} & 4 \\

{} & \nearrow & {} \\

2 & \to & 6 \\

{} & \searrow & {} \\

{} & {} & 8 \\

\end{array}, so

$\displaystyle \begin{array}{*{20}c}

{} & {} & 4 \\

{} & \nearrow & {} \\

2 & \to & 6 \\

{} & \searrow & {} \\

{} & {} & 8 \\

\end{array}$
