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 22,201,223, 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 | 22,201,223 | |
| -1 | -22,201,223 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,201,223.
Example:
1 x 22,201,223 = 22,201,223
and
-1 x -22,201,223 = 22,201,223
Notice both answers equal 22,201,223
With that explanation out of the way, let's continue. Next, we take the number 22,201,223 and divide it by 2:
22,201,223 ÷ 2 = 11,100,611.5
If the quotient is a whole number, then 2 and 11,100,611.5 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 | 22,201,223 | |
| -1 | -22,201,223 |
Now, we try dividing 22,201,223 by 3:
22,201,223 ÷ 3 = 7,400,407.6667
If the quotient is a whole number, then 3 and 7,400,407.6667 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 | 22,201,223 | |
| -1 | -22,201,223 |
Let's try dividing by 4:
22,201,223 ÷ 4 = 5,550,305.75
If the quotient is a whole number, then 4 and 5,550,305.75 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 | 22,201,223 | |
| -1 | 22,201,223 |
If you did it right, you will end up with this table:
| 1 | 11 | 53 | 113 | 337 | 583 | 1,243 | 3,707 | 5,989 | 17,861 | 38,081 | 65,879 | 196,471 | 418,891 | 2,018,293 | 22,201,223 |
| -1 | -11 | -53 | -113 | -337 | -583 | -1,243 | -3,707 | -5,989 | -17,861 | -38,081 | -65,879 | -196,471 | -418,891 | -2,018,293 | -22,201,223 |
