Problem B. 4687. (February 2015)

B. 4687. Samson wrote the number 123456789 on a sheet of paper. Then he may or may not have placed a multiplication sign between any two consecutive digits. (He may have used several of them, or none at all.) By reading the digits between multiplication signs as a single number, he obtained a product of numbers. For example, $\displaystyle 1234 \cdot 56 \cdot 789$. What is the maximum possible value of the number obtained in this way?
