Here we answer the question: "What two numbers multiply to 623 and add up to -624?"

The answer to your question is:

-623 and -1

Below we illustrate and prove that -623 and -1 multiply to 623 and add up to -624:

-623 × -1 = 623
-623 + -1 = -624

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

x² - 624x + 623 = 0

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

(x - 623 ) (x - 1)

To summarize, since -623 and -1 multiply to 623 and add up -624, you know that the following is true:

x² - 624x + 623 = (x - 623 ) (x - 1)
