The factors of 25 are 1,5 and 25. Thus it can be a product of any of these numbers multiplied by whatever value is 25 divided by that number. 25 is a product of: 1x25 5x5 25x1

25 can be either the product of 1 and 25, or the product of 5 and 5. Since there are two digits in the number, the answer can only be 55. This makes sense, since 55 is divisible by 5, and the product of 5 and 5 is 25.
