Let's denote the two numbers as x and y. We can create a system of equations based on the given conditions: xy = 56 and x + y = 30. To solve this system, we can use substitution or elimination methods. By factoring 56 into its prime factors (2^3 * 7), we can determine that the two numbers are 14 and 4, as they multiply to 56 and add up to 30.
The 8 factors of 56 are 1, 2, 4, 7, 8, 14, 28, and 56. 2 and 8 add up to 10. Also, 1, 2, and 7 add up to 10.

Oh honey, you must be new to the math game. The only way to add two prime numbers and get 56 is if you're playing make-believe. Prime numbers are loners, they don't like to share their factors with anyone else. So, sorry to burst your bubble, but there are no two prime numbers that can add up to 56. Better luck next time!
56 + 56 + 28 + 8 + 2 + 1 = 151
-54 and -2 aren't technically factors of 108, but they will satisfy this problem.

Factors are multiplied, not added. The question needs to be something like, "Which two factors of thirty add up to 11?" The answer would then be 5 and 6.
