How do I find the factor combinations of the number 40,777,260?

Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 40,777,260, it is easier to work with a table - it's called factoring from the outside in.

Outside in Factoring

We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.

1 40,777,260
-1 -40,777,260

Why are the negative numbers included?

When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 40,777,260.

Example:
1 x 40,777,260 = 40,777,260
and
-1 x -40,777,260 = 40,777,260
Notice both answers equal 40,777,260

With that explanation out of the way, let's continue. Next, we take the number 40,777,260 and divide it by 2:

40,777,260 ÷ 2 = 20,388,630

If the quotient is a whole number, then 2 and 20,388,630 are factors. In this case, the quotient is a whole number. Write them in the table inside the other two factors like the below example. Don't forget to write the negative numbers too!

Here is what our table should look like at this step:

1 2 20,388,630 40,777,260
-1 -2 -20,388,630 -40,777,260

Now, we try dividing 40,777,260 by 3:

40,777,260 ÷ 3 = 13,592,420

If the quotient is a whole number, then 3 and 13,592,420 are factors. In this case, the quotient is a whole number. Write them in the table inside the other two factors like the below example. Don't forget to write the negative numbers too!

Here is what our table should look like at this step:

1 2 3 13,592,420 20,388,630 40,777,260
-1 -2 -3 -13,592,420 -20,388,630 -40,777,260

Let's try dividing by 4:

40,777,260 ÷ 4 = 10,194,315

If the quotient is a whole number, then 4 and 10,194,315 are factors. In this case, the quotient is a whole number. Write them in the table inside the other two factors like the below example. Don't forget to write the negative numbers too!

Here is what our table should look like at this step:

1 2 3 4 10,194,315 13,592,420 20,388,630 40,777,260
-1 -2 -3 -4 -10,194,315 -13,592,420 -20,388,630 40,777,260
Keep dividing by the next highest number until you cannot divide anymore.

If you did it right, you will end up with this table:
