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 16,857,685, 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 | 16,857,685 | |
| -1 | -16,857,685 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,857,685.
Example:
1 x 16,857,685 = 16,857,685
and
-1 x -16,857,685 = 16,857,685
Notice both answers equal 16,857,685
With that explanation out of the way, let's continue. Next, we take the number 16,857,685 and divide it by 2:
16,857,685 ÷ 2 = 8,428,842.5
If the quotient is a whole number, then 2 and 8,428,842.5 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 | 16,857,685 | |
| -1 | -16,857,685 |
Now, we try dividing 16,857,685 by 3:
16,857,685 ÷ 3 = 5,619,228.3333
If the quotient is a whole number, then 3 and 5,619,228.3333 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 | 16,857,685 | |
| -1 | -16,857,685 |
Let's try dividing by 4:
16,857,685 ÷ 4 = 4,214,421.25
If the quotient is a whole number, then 4 and 4,214,421.25 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 | 16,857,685 | |
| -1 | 16,857,685 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 223 | 1,115 | 1,163 | 2,899 | 5,815 | 14,495 | 15,119 | 75,595 | 259,349 | 1,296,745 | 3,371,537 | 16,857,685 |
| -1 | -5 | -13 | -65 | -223 | -1,115 | -1,163 | -2,899 | -5,815 | -14,495 | -15,119 | -75,595 | -259,349 | -1,296,745 | -3,371,537 | -16,857,685 |
