How do I find the factor combinations of the number 11,405,436?

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 11,405,436, 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 11,405,436
-1 -11,405,436

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 11,405,436.

Example:
1 x 11,405,436 = 11,405,436
and
-1 x -11,405,436 = 11,405,436
Notice both answers equal 11,405,436

With that explanation out of the way, let's continue. Next, we take the number 11,405,436 and divide it by 2:

11,405,436 ÷ 2 = 5,702,718

If the quotient is a whole number, then 2 and 5,702,718 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 5,702,718 11,405,436
-1 -2 -5,702,718 -11,405,436

Now, we try dividing 11,405,436 by 3:

11,405,436 ÷ 3 = 3,801,812

If the quotient is a whole number, then 3 and 3,801,812 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 3,801,812 5,702,718 11,405,436
-1 -2 -3 -3,801,812 -5,702,718 -11,405,436

Let's try dividing by 4:

11,405,436 ÷ 4 = 2,851,359

If the quotient is a whole number, then 4 and 2,851,359 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 2,851,359 3,801,812 5,702,718 11,405,436
-1 -2 -3 -4 -2,851,359 -3,801,812 -5,702,718 11,405,436
Keep dividing by the next highest number until you cannot divide anymore.

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