2. (4 points) Fill in the $\square$ with the numbers $2, 4, 6, 8$ to form a multiplication equation.
(1) To make the product the largest, how can you fill it? $\square$
$\square$ $\times$ $\square$
(2) To make the product the smallest, how can you fill it? $\square$
$\square$ $\square \times$ $\square$
$\square$
【Solution】Solution: (1) To make the product the largest, there are four possibilities: $864 \times 2=1728, 862 \times 4=3448, 842 \times 6=5052$, $642 \times 8=5136$,

From this, we can see that the product of $642 \times 8$ is the largest.
(2) To make the product the smallest, there are four possibilities: $468 \times 2=938, 268 \times 4=1072, 248 \times 6=1488, 246 \times 8=1968$, from this we can see that the product of $468 \times 2$ is the smallest.
