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 13,476,665, 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 | 13,476,665 | |
| -1 | -13,476,665 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,476,665.
Example:
1 x 13,476,665 = 13,476,665
and
-1 x -13,476,665 = 13,476,665
Notice both answers equal 13,476,665
With that explanation out of the way, let's continue. Next, we take the number 13,476,665 and divide it by 2:
13,476,665 ÷ 2 = 6,738,332.5
If the quotient is a whole number, then 2 and 6,738,332.5 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 | 13,476,665 | |
| -1 | -13,476,665 |
Now, we try dividing 13,476,665 by 3:
13,476,665 ÷ 3 = 4,492,221.6667
If the quotient is a whole number, then 3 and 4,492,221.6667 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 | 13,476,665 | |
| -1 | -13,476,665 |
Let's try dividing by 4:
13,476,665 ÷ 4 = 3,369,166.25
If the quotient is a whole number, then 4 and 3,369,166.25 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 | 13,476,665 | |
| -1 | 13,476,665 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 331 | 479 | 1,655 | 2,395 | 5,627 | 8,143 | 28,135 | 40,715 | 158,549 | 792,745 | 2,695,333 | 13,476,665 |
| -1 | -5 | -17 | -85 | -331 | -479 | -1,655 | -2,395 | -5,627 | -8,143 | -28,135 | -40,715 | -158,549 | -792,745 | -2,695,333 | -13,476,665 |
