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 13,326,115, 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 | 13,326,115 | |
| -1 | -13,326,115 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,326,115.
Example:
1 x 13,326,115 = 13,326,115
and
-1 x -13,326,115 = 13,326,115
Notice both answers equal 13,326,115
With that explanation out of the way, let's continue. Next, we take the number 13,326,115 and divide it by 2:
13,326,115 ÷ 2 = 6,663,057.5
If the quotient is a whole number, then 2 and 6,663,057.5 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 | 13,326,115 | |
| -1 | -13,326,115 |
Now, we try dividing 13,326,115 by 3:
13,326,115 ÷ 3 = 4,442,038.3333
If the quotient is a whole number, then 3 and 4,442,038.3333 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 | 13,326,115 | |
| -1 | -13,326,115 |
Let's try dividing by 4:
13,326,115 ÷ 4 = 3,331,528.75
If the quotient is a whole number, then 4 and 3,331,528.75 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 | 13,326,115 | |
| -1 | 13,326,115 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 79 | 395 | 869 | 3,067 | 4,345 | 15,335 | 33,737 | 168,685 | 242,293 | 1,211,465 | 2,665,223 | 13,326,115 |
| -1 | -5 | -11 | -55 | -79 | -395 | -869 | -3,067 | -4,345 | -15,335 | -33,737 | -168,685 | -242,293 | -1,211,465 | -2,665,223 | -13,326,115 |
