What two numbers multiply to 728 and add up to 111?

Here we answer the question: "What two numbers multiply to 728 and add up to 111?"

The answer to your question is:

7 and 104

Below we illustrate and prove that 7 and 104 multiply to 728 and add up to 111:

7 × 104 = 728
7 + 104 = 111

Are you asking because you are trying to figure out how to factor the following quadratic equation?

x² + 111x + 728 = 0

If so, the solution to factor the quadratic equation above is:

(x + 7 ) (x + 104)

To summarize, since 7 and 104 multiply to 728 and add up 111, you know that the following is true:

x² + 111x + 728 = (x + 7 ) (x + 104)
