There are 4 mathematicians - Brahma, Sachin, Prashant and Nakul - having lunch in a hotel. Suddenly, Brahma thinks of 2 integer numbers greater than 1 and says, "The sum of the numbers is..." and he whispers the sum to Sachin. Then he says, "The product of the numbers is..." and he whispers the product to Prashant. After that, the following conversation takes place :

Sachin : Prashant, I don't think that we know the numbers.
Prashant : Aha! Now I know the numbers.
Sachin : Oh, now I also know the numbers.
Nakul : Now I also know the numbers.
