How do I find the factor combinations of the number 263,163,024?
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 263,163,024, 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.

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 263,163,024.
Example:
1 x 263,163,024 = 263,163,024
and
-1 x -263,163,024 = 263,163,024
Notice both answers equal 263,163,024
With that explanation out of the way, let's continue. Next, we take the number 263,163,024 and divide it by 2:
263,163,024 ÷ 2 = 131,581,512
If the quotient is a whole number, then 2 and 131,581,512 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:
Now, we try dividing 263,163,024 by 3:
263,163,024 ÷ 3 = 87,721,008
If the quotient is a whole number, then 3 and 87,721,008 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:
Let's try dividing by 4:
263,163,024 ÷ 4 = 65,790,756
If the quotient is a whole number, then 4 and 65,790,756 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:
Keep dividing by the next highest number until you cannot divide anymore.
If you did it right, you will end up with this table:
