What two numbers multiply to 427 and add up to 428?

Here we answer the question: "What two numbers multiply to 427 and add up to 428?"

The answer to your question is:

1 and 427

Below we illustrate and prove that 1 and 427 multiply to 427 and add up to 428:

1 × 427 = 427
1 + 427 = 428

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

x² + 428x + 427 = 0

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

(x + 1 ) (x + 427)

To summarize, since 1 and 427 multiply to 427 and add up 428, you know that the following is true:

x² + 428x + 427 = (x + 1 ) (x + 427)
