\[ \large{\begin{array}{ccccccc} && & & & & \square & 2\\ \times && & & & & \square &4\\ \hline & & & & \square & \square & \color{red}\square &8\\ \hline \end{array}} \]
The above shows an incomplete long multiplication. Each square represents a distinct non-zero digit other than 2, 4, and 8 already used in the long multiplication. What is the value that represents the red square?
