How do I find the factor combinations of the number 40,756,404?

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 40,756,404, 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 40,756,404
-1 -40,756,404

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 40,756,404.

Example:
1 x 40,756,404 = 40,756,404
and
-1 x -40,756,404 = 40,756,404
Notice both answers equal 40,756,404

With that explanation out of the way, let's continue. Next, we take the number 40,756,404 and divide it by 2:

40,756,404 ÷ 2 = 20,378,202

If the quotient is a whole number, then 2 and 20,378,202 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 20,378,202 40,756,404
-1 -2 -20,378,202 -40,756,404

Now, we try dividing 40,756,404 by 3:

40,756,404 ÷ 3 = 13,585,468

If the quotient is a whole number, then 3 and 13,585,468 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 13,585,468 20,378,202 40,756,404
-1 -2 -3 -13,585,468 -20,378,202 -40,756,404

Let's try dividing by 4:

40,756,404 ÷ 4 = 10,189,101

If the quotient is a whole number, then 4 and 10,189,101 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 10,189,101 13,585,468 20,378,202 40,756,404
-1 -2 -3 -4 -10,189,101 -13,585,468 -20,378,202 40,756,404
Keep dividing by the next highest number until you cannot divide anymore.

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