How do I find the factor combinations of the number 105,404,502?

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 105,404,502, 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.

1 105,404,502
-1 -105,404,502

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 105,404,502.

Example:
1 x 105,404,502 = 105,404,502
and
-1 x -105,404,502 = 105,404,502
Notice both answers equal 105,404,502

With that explanation out of the way, let's continue. Next, we take the number 105,404,502 and divide it by 2:

105,404,502 ÷ 2 = 52,702,251

If the quotient is a whole number, then 2 and 52,702,251 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 52,702,251 105,404,502
-1 -2 -52,702,251 -105,404,502

Now, we try dividing 105,404,502 by 3:

105,404,502 ÷ 3 = 35,134,834

If the quotient is a whole number, then 3 and 35,134,834 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 35,134,834 52,702,251 105,404,502
-1 -2 -3 -35,134,834 -52,702,251 -105,404,502

Let's try dividing by 4:

105,404,502 ÷ 4 = 26,351,125.5

If the quotient is a whole number, then 4 and 26,351,125.5 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 3 35,134,834 52,702,251 105,404,502
-1 -2 -3 -35,134,834 -52,702,251 105,404,502
Keep dividing by the next highest number until you cannot divide anymore.

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