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 13,312,013, 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 | 13,312,013 | |
| -1 | -13,312,013 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,312,013.
Example:
1 x 13,312,013 = 13,312,013
and
-1 x -13,312,013 = 13,312,013
Notice both answers equal 13,312,013
With that explanation out of the way, let's continue. Next, we take the number 13,312,013 and divide it by 2:
13,312,013 ÷ 2 = 6,656,006.5
If the quotient is a whole number, then 2 and 6,656,006.5 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 | 13,312,013 | |
| -1 | -13,312,013 |
Now, we try dividing 13,312,013 by 3:
13,312,013 ÷ 3 = 4,437,337.6667
If the quotient is a whole number, then 3 and 4,437,337.6667 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 | 13,312,013 | |
| -1 | -13,312,013 |
Let's try dividing by 4:
13,312,013 ÷ 4 = 3,328,003.25
If the quotient is a whole number, then 4 and 3,328,003.25 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 | 13,312,013 | |
| -1 | 13,312,013 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 127 | 143 | 733 | 1,397 | 1,651 | 8,063 | 9,529 | 18,161 | 93,091 | 104,819 | 1,024,001 | 1,210,183 | 13,312,013 |
| -1 | -11 | -13 | -127 | -143 | -733 | -1,397 | -1,651 | -8,063 | -9,529 | -18,161 | -93,091 | -104,819 | -1,024,001 | -1,210,183 | -13,312,013 |
