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 13,613,633, it is easier to work with a table - it's called factoring from the outside in.
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 | 13,613,633 | |
| -1 | -13,613,633 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,613,633.
Example:
1 x 13,613,633 = 13,613,633
and
-1 x -13,613,633 = 13,613,633
Notice both answers equal 13,613,633
With that explanation out of the way, let's continue. Next, we take the number 13,613,633 and divide it by 2:
13,613,633 ÷ 2 = 6,806,816.5
If the quotient is a whole number, then 2 and 6,806,816.5 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 | 13,613,633 | |
| -1 | -13,613,633 |
Now, we try dividing 13,613,633 by 3:
13,613,633 ÷ 3 = 4,537,877.6667
If the quotient is a whole number, then 3 and 4,537,877.6667 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 | 13,613,633 | |
| -1 | -13,613,633 |
Let's try dividing by 4:
13,613,633 ÷ 4 = 3,403,408.25
If the quotient is a whole number, then 4 and 3,403,408.25 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 | 13,613,633 | |
| -1 | 13,613,633 |
If you did it right, you will end up with this table:
| 1 | 11 | 19 | 53 | 209 | 583 | 1,007 | 1,229 | 11,077 | 13,519 | 23,351 | 65,137 | 256,861 | 716,507 | 1,237,603 | 13,613,633 |
| -1 | -11 | -19 | -53 | -209 | -583 | -1,007 | -1,229 | -11,077 | -13,519 | -23,351 | -65,137 | -256,861 | -716,507 | -1,237,603 | -13,613,633 |
