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 22,115,029, 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 | 22,115,029 | |
| -1 | -22,115,029 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,115,029.
Example:
1 x 22,115,029 = 22,115,029
and
-1 x -22,115,029 = 22,115,029
Notice both answers equal 22,115,029
With that explanation out of the way, let's continue. Next, we take the number 22,115,029 and divide it by 2:
22,115,029 ÷ 2 = 11,057,514.5
If the quotient is a whole number, then 2 and 11,057,514.5 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 | 22,115,029 | |
| -1 | -22,115,029 |
Now, we try dividing 22,115,029 by 3:
22,115,029 ÷ 3 = 7,371,676.3333
If the quotient is a whole number, then 3 and 7,371,676.3333 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 | 22,115,029 | |
| -1 | -22,115,029 |
Let's try dividing by 4:
22,115,029 ÷ 4 = 5,528,757.25
If the quotient is a whole number, then 4 and 5,528,757.25 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 | 22,115,029 | |
| -1 | 22,115,029 |
If you did it right, you will end up with this table:
| 1 | 23 | 43 | 59 | 379 | 989 | 1,357 | 2,537 | 8,717 | 16,297 | 22,361 | 58,351 | 374,831 | 514,303 | 961,523 | 22,115,029 |
| -1 | -23 | -43 | -59 | -379 | -989 | -1,357 | -2,537 | -8,717 | -16,297 | -22,361 | -58,351 | -374,831 | -514,303 | -961,523 | -22,115,029 |
