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 22,127,443, 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 | 22,127,443 | |
| -1 | -22,127,443 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,127,443.
Example:
1 x 22,127,443 = 22,127,443
and
-1 x -22,127,443 = 22,127,443
Notice both answers equal 22,127,443
With that explanation out of the way, let's continue. Next, we take the number 22,127,443 and divide it by 2:
22,127,443 ÷ 2 = 11,063,721.5
If the quotient is a whole number, then 2 and 11,063,721.5 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 | 22,127,443 | |
| -1 | -22,127,443 |
Now, we try dividing 22,127,443 by 3:
22,127,443 ÷ 3 = 7,375,814.3333
If the quotient is a whole number, then 3 and 7,375,814.3333 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 | 22,127,443 | |
| -1 | -22,127,443 |
Let's try dividing by 4:
22,127,443 ÷ 4 = 5,531,860.75
If the quotient is a whole number, then 4 and 5,531,860.75 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 | 22,127,443 | |
| -1 | 22,127,443 |
If you did it right, you will end up with this table:
| 1 | 13 | 37 | 179 | 257 | 481 | 2,327 | 3,341 | 6,623 | 9,509 | 46,003 | 86,099 | 123,617 | 598,039 | 1,702,111 | 22,127,443 |
| -1 | -13 | -37 | -179 | -257 | -481 | -2,327 | -3,341 | -6,623 | -9,509 | -46,003 | -86,099 | -123,617 | -598,039 | -1,702,111 | -22,127,443 |
