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 22,240,205, 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 | 22,240,205 | |
| -1 | -22,240,205 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,240,205.
Example:
1 x 22,240,205 = 22,240,205
and
-1 x -22,240,205 = 22,240,205
Notice both answers equal 22,240,205
With that explanation out of the way, let's continue. Next, we take the number 22,240,205 and divide it by 2:
22,240,205 ÷ 2 = 11,120,102.5
If the quotient is a whole number, then 2 and 11,120,102.5 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 | 22,240,205 | |
| -1 | -22,240,205 |
Now, we try dividing 22,240,205 by 3:
22,240,205 ÷ 3 = 7,413,401.6667
If the quotient is a whole number, then 3 and 7,413,401.6667 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 | 22,240,205 | |
| -1 | -22,240,205 |
Let's try dividing by 4:
22,240,205 ÷ 4 = 5,560,051.25
If the quotient is a whole number, then 4 and 5,560,051.25 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 | 22,240,205 | |
| -1 | 22,240,205 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 463 | 739 | 2,315 | 3,695 | 6,019 | 9,607 | 30,095 | 48,035 | 342,157 | 1,710,785 | 4,448,041 | 22,240,205 |
| -1 | -5 | -13 | -65 | -463 | -739 | -2,315 | -3,695 | -6,019 | -9,607 | -30,095 | -48,035 | -342,157 | -1,710,785 | -4,448,041 | -22,240,205 |
