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 22,115,023, 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 | 22,115,023 | |
| -1 | -22,115,023 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,115,023.
Example:
1 x 22,115,023 = 22,115,023
and
-1 x -22,115,023 = 22,115,023
Notice both answers equal 22,115,023
With that explanation out of the way, let's continue. Next, we take the number 22,115,023 and divide it by 2:
22,115,023 ÷ 2 = 11,057,511.5
If the quotient is a whole number, then 2 and 11,057,511.5 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 | 22,115,023 | |
| -1 | -22,115,023 |
Now, we try dividing 22,115,023 by 3:
22,115,023 ÷ 3 = 7,371,674.3333
If the quotient is a whole number, then 3 and 7,371,674.3333 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 | 22,115,023 | |
| -1 | -22,115,023 |
Let's try dividing by 4:
22,115,023 ÷ 4 = 5,528,755.75
If the quotient is a whole number, then 4 and 5,528,755.75 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 | 22,115,023 | |
| -1 | 22,115,023 |
If you did it right, you will end up with this table:
| 1 | 7 | 29 | 49 | 79 | 197 | 203 | 553 | 1,379 | 1,421 | 2,291 | 3,871 | 5,713 | 9,653 | 15,563 | 16,037 | 39,991 | 108,941 | 112,259 | 279,937 | 451,327 | 762,587 | 3,159,289 | 22,115,023 |
| -1 | -7 | -29 | -49 | -79 | -197 | -203 | -553 | -1,379 | -1,421 | -2,291 | -3,871 | -5,713 | -9,653 | -15,563 | -16,037 | -39,991 | -108,941 | -112,259 | -279,937 | -451,327 | -762,587 | -3,159,289 | -22,115,023 |
