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 22,431,143, 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 | 22,431,143 | |
| -1 | -22,431,143 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,431,143.
Example:
1 x 22,431,143 = 22,431,143
and
-1 x -22,431,143 = 22,431,143
Notice both answers equal 22,431,143
With that explanation out of the way, let's continue. Next, we take the number 22,431,143 and divide it by 2:
22,431,143 ÷ 2 = 11,215,571.5
If the quotient is a whole number, then 2 and 11,215,571.5 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 | 22,431,143 | |
| -1 | -22,431,143 |
Now, we try dividing 22,431,143 by 3:
22,431,143 ÷ 3 = 7,477,047.6667
If the quotient is a whole number, then 3 and 7,477,047.6667 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 | 22,431,143 | |
| -1 | -22,431,143 |
Let's try dividing by 4:
22,431,143 ÷ 4 = 5,607,785.75
If the quotient is a whole number, then 4 and 5,607,785.75 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 | 22,431,143 | |
| -1 | 22,431,143 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 119 | 233 | 809 | 1,631 | 3,961 | 5,663 | 13,753 | 27,727 | 96,271 | 188,497 | 1,319,479 | 3,204,449 | 22,431,143 |
| -1 | -7 | -17 | -119 | -233 | -809 | -1,631 | -3,961 | -5,663 | -13,753 | -27,727 | -96,271 | -188,497 | -1,319,479 | -3,204,449 | -22,431,143 |
