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 16,822,013, 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 | 16,822,013 | |
| -1 | -16,822,013 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,822,013.
Example:
1 x 16,822,013 = 16,822,013
and
-1 x -16,822,013 = 16,822,013
Notice both answers equal 16,822,013
With that explanation out of the way, let's continue. Next, we take the number 16,822,013 and divide it by 2:
16,822,013 ÷ 2 = 8,411,006.5
If the quotient is a whole number, then 2 and 8,411,006.5 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 | 16,822,013 | |
| -1 | -16,822,013 |
Now, we try dividing 16,822,013 by 3:
16,822,013 ÷ 3 = 5,607,337.6667
If the quotient is a whole number, then 3 and 5,607,337.6667 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 | 16,822,013 | |
| -1 | -16,822,013 |
Let's try dividing by 4:
16,822,013 ÷ 4 = 4,205,503.25
If the quotient is a whole number, then 4 and 4,205,503.25 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 | 16,822,013 | |
| -1 | 16,822,013 |
If you did it right, you will end up with this table:
| 1 | 13 | 37 | 41 | 481 | 533 | 853 | 1,517 | 11,089 | 19,721 | 31,561 | 34,973 | 410,293 | 454,649 | 1,294,001 | 16,822,013 |
| -1 | -13 | -37 | -41 | -481 | -533 | -853 | -1,517 | -11,089 | -19,721 | -31,561 | -34,973 | -410,293 | -454,649 | -1,294,001 | -16,822,013 |
