What two numbers multiply to 620 and add up to 621?

Here we answer the question: "What two numbers multiply to 620 and add up to 621?"

The answer to your question is:

1 and 620

Below we illustrate and prove that 1 and 620 multiply to 620 and add up to 621:

1 × 620 = 620
1 + 620 = 621

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

x² + 621x + 620 = 0

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

(x + 1 ) (x + 620)

To summarize, since 1 and 620 multiply to 620 and add up 621, you know that the following is true:

x² + 621x + 620 = (x + 1 ) (x + 620)
