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 13,316,105, 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 | 13,316,105 | |
| -1 | -13,316,105 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,316,105.
Example:
1 x 13,316,105 = 13,316,105
and
-1 x -13,316,105 = 13,316,105
Notice both answers equal 13,316,105
With that explanation out of the way, let's continue. Next, we take the number 13,316,105 and divide it by 2:
13,316,105 ÷ 2 = 6,658,052.5
If the quotient is a whole number, then 2 and 6,658,052.5 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 | 13,316,105 | |
| -1 | -13,316,105 |
Now, we try dividing 13,316,105 by 3:
13,316,105 ÷ 3 = 4,438,701.6667
If the quotient is a whole number, then 3 and 4,438,701.6667 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 | 13,316,105 | |
| -1 | -13,316,105 |
Let's try dividing by 4:
13,316,105 ÷ 4 = 3,329,026.25
If the quotient is a whole number, then 4 and 3,329,026.25 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 | 13,316,105 | |
| -1 | 13,316,105 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 83 | 415 | 913 | 2,917 | 4,565 | 14,585 | 32,087 | 160,435 | 242,111 | 1,210,555 | 2,663,221 | 13,316,105 |
| -1 | -5 | -11 | -55 | -83 | -415 | -913 | -2,917 | -4,565 | -14,585 | -32,087 | -160,435 | -242,111 | -1,210,555 | -2,663,221 | -13,316,105 |
