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 22,040,789, 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 | 22,040,789 | |
| -1 | -22,040,789 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,040,789.
Example:
1 x 22,040,789 = 22,040,789
and
-1 x -22,040,789 = 22,040,789
Notice both answers equal 22,040,789
With that explanation out of the way, let's continue. Next, we take the number 22,040,789 and divide it by 2:
22,040,789 ÷ 2 = 11,020,394.5
If the quotient is a whole number, then 2 and 11,020,394.5 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 | 22,040,789 | |
| -1 | -22,040,789 |
Now, we try dividing 22,040,789 by 3:
22,040,789 ÷ 3 = 7,346,929.6667
If the quotient is a whole number, then 3 and 7,346,929.6667 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 | 22,040,789 | |
| -1 | -22,040,789 |
Let's try dividing by 4:
22,040,789 ÷ 4 = 5,510,197.25
If the quotient is a whole number, then 4 and 5,510,197.25 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 | 22,040,789 | |
| -1 | 22,040,789 |
If you did it right, you will end up with this table:
| 1 | 17 | 37 | 67 | 523 | 629 | 1,139 | 2,479 | 8,891 | 19,351 | 35,041 | 42,143 | 328,967 | 595,697 | 1,296,517 | 22,040,789 |
| -1 | -17 | -37 | -67 | -523 | -629 | -1,139 | -2,479 | -8,891 | -19,351 | -35,041 | -42,143 | -328,967 | -595,697 | -1,296,517 | -22,040,789 |
