Here we answer the question: "What two numbers multiply to 656 and add up to 657?"

The answer to your question is:

1 and 656

Below we illustrate and prove that 1 and 656 multiply to 656 and add up to 657:

1 × 656 = 656
1 + 656 = 657

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

x² + 657x + 656 = 0

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

(x + 1 ) (x + 656)

To summarize, since 1 and 656 multiply to 656 and add up 657, you know that the following is true:

x² + 657x + 656 = (x + 1 ) (x + 656)
