How do I find the factor combinations of the number 105,253,644?

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 105,253,644, 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.

1 105,253,644
-1 -105,253,644

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 105,253,644.

Example:
1 x 105,253,644 = 105,253,644
and
-1 x -105,253,644 = 105,253,644
Notice both answers equal 105,253,644

With that explanation out of the way, let's continue. Next, we take the number 105,253,644 and divide it by 2:

105,253,644 ÷ 2 = 52,626,822

If the quotient is a whole number, then 2 and 52,626,822 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 52,626,822 105,253,644
-1 -2 -52,626,822 -105,253,644

Now, we try dividing 105,253,644 by 3:

105,253,644 ÷ 3 = 35,084,548

If the quotient is a whole number, then 3 and 35,084,548 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 35,084,548 52,626,822 105,253,644
-1 -2 -3 -35,084,548 -52,626,822 -105,253,644

Let's try dividing by 4:

105,253,644 ÷ 4 = 26,313,411

If the quotient is a whole number, then 4 and 26,313,411 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 26,313,411 35,084,548 52,626,822 105,253,644
-1 -2 -3 -4 -26,313,411 -35,084,548 -52,626,822 105,253,644
Keep dividing by the next highest number until you cannot divide anymore.

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