How do I find the factor combinations of the number 40,051,328?

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 40,051,328, 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 40,051,328
-1 -40,051,328

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 40,051,328.

Example:
1 x 40,051,328 = 40,051,328
and
-1 x -40,051,328 = 40,051,328
Notice both answers equal 40,051,328

With that explanation out of the way, let's continue. Next, we take the number 40,051,328 and divide it by 2:

40,051,328 ÷ 2 = 20,025,664

If the quotient is a whole number, then 2 and 20,025,664 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 20,025,664 40,051,328
-1 -2 -20,025,664 -40,051,328

Now, we try dividing 40,051,328 by 3:

40,051,328 ÷ 3 = 13,350,442.6667

If the quotient is a whole number, then 3 and 13,350,442.6667 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.

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

1 2 20,025,664 40,051,328
-1 -2 -20,025,664 -40,051,328

Let's try dividing by 4:

40,051,328 ÷ 4 = 10,012,832

If the quotient is a whole number, then 4 and 10,012,832 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 4 10,012,832 20,025,664 40,051,328
-1 -2 -4 -10,012,832 -20,025,664 40,051,328
Keep dividing by the next highest number until you cannot divide anymore.

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