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 13,312,331, 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 | 13,312,331 | |
| -1 | -13,312,331 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,312,331.
Example:
1 x 13,312,331 = 13,312,331
and
-1 x -13,312,331 = 13,312,331
Notice both answers equal 13,312,331
With that explanation out of the way, let's continue. Next, we take the number 13,312,331 and divide it by 2:
13,312,331 ÷ 2 = 6,656,165.5
If the quotient is a whole number, then 2 and 6,656,165.5 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 | 13,312,331 | |
| -1 | -13,312,331 |
Now, we try dividing 13,312,331 by 3:
13,312,331 ÷ 3 = 4,437,443.6667
If the quotient is a whole number, then 3 and 4,437,443.6667 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 | 13,312,331 | |
| -1 | -13,312,331 |
Let's try dividing by 4:
13,312,331 ÷ 4 = 3,328,082.75
If the quotient is a whole number, then 4 and 3,328,082.75 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 | 13,312,331 | |
| -1 | 13,312,331 |
If you did it right, you will end up with this table:
| 1 | 19 | 23 | 41 | 437 | 743 | 779 | 943 | 14,117 | 17,089 | 17,917 | 30,463 | 324,691 | 578,797 | 700,649 | 13,312,331 |
| -1 | -19 | -23 | -41 | -437 | -743 | -779 | -943 | -14,117 | -17,089 | -17,917 | -30,463 | -324,691 | -578,797 | -700,649 | -13,312,331 |
