How do I find the factor combinations of the number 40,353,444?

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 40,353,444, 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 40,353,444
-1 -40,353,444

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 40,353,444.

Example:
1 x 40,353,444 = 40,353,444
and
-1 x -40,353,444 = 40,353,444
Notice both answers equal 40,353,444

With that explanation out of the way, let's continue. Next, we take the number 40,353,444 and divide it by 2:

40,353,444 ÷ 2 = 20,176,722

If the quotient is a whole number, then 2 and 20,176,722 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 20,176,722 40,353,444
-1 -2 -20,176,722 -40,353,444

Now, we try dividing 40,353,444 by 3:

40,353,444 ÷ 3 = 13,451,148

If the quotient is a whole number, then 3 and 13,451,148 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 13,451,148 20,176,722 40,353,444
-1 -2 -3 -13,451,148 -20,176,722 -40,353,444

Let's try dividing by 4:

40,353,444 ÷ 4 = 10,088,361

If the quotient is a whole number, then 4 and 10,088,361 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 10,088,361 13,451,148 20,176,722 40,353,444
-1 -2 -3 -4 -10,088,361 -13,451,148 -20,176,722 40,353,444
Keep dividing by the next highest number until you cannot divide anymore.

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