What two numbers multiply to 623 and add up to 624?

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

The answer to your question is:

1 and 623

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

1 × 623 = 623
1 + 623 = 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 + 1 ) (x + 623)

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

x² + 624x + 623 = (x + 1 ) (x + 623)
