For any integer $x$, $\boxed{x}$ is defined to be the product of all its factors greater than 1 not including $x$. Find $\fbox{12}$.
To find $\fbox{12}$, I need to identify all the factors of 12 that are greater than 1 and not equal to 12, and then multiply them together. The factors of 12 are 1, 2, 3, 4, 6, and 12. Of these, 1 and 12 are not allowed, so I only need to consider 2, 3, 4, and 6. Multiplying these factors together, I get $\fbox{12} = 2 \times 3 \times 4 \times 6 = 144$.
