In the year , the United States will host the International Mathematical Olympiad. Let and be distinct positive integers such that the product . What is the largest possible value of the sum ?
Solution 1 (Verifying a Statement)
First, we need to recognize that a number is going to be lowest only if, of the factors, two of them are small. If we want to make sure that this is correct, we could test with a smaller number, like . It becomes much more clear that this is true, and in this situation, the value of would be . Now, we use this process on to get as our factors. Hence, we have

Solution 2
The sum is the highest if two factors are the lowest.
So, and .
Solution 3 (Answer Choices)
