Ash, Ben and Charles are playing a game about numbers. After Ash randomly picked 2 natural numbers in \left { 1,2,3,...,9 \right }{1,2,3,...,9} (the two numbers can be the same), Ash showed Ben the sum of two numbers only and showed Charles the product of two numbers only. Here is the conversation between Ben and Charles:
Ben: I don't know which two numbers Ash had picked, but I am sure that you (Charles) don't know either.
Charles: I don't know either at first but I know now. I also know that my showed result is greater than yours.
Ben: Then I know these numbers now.
What is the result that Ash showed Ben?
