Which number is greater then 25 and has the most factors?

Answer 1

There is no such number with "most factors"; if you have a number with a certain number of factors, you can always multiply it by 2, or by 3, etc., to get another number that has even more factors.

Answer 2

There is no such number. If any number lays claim to have the most factors, then 2 times that number will have twice as many. That process can go on for ever.
