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 23,882,105, 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 | 23,882,105 | |
| -1 | -23,882,105 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,882,105.
Example:
1 x 23,882,105 = 23,882,105
and
-1 x -23,882,105 = 23,882,105
Notice both answers equal 23,882,105
With that explanation out of the way, let's continue. Next, we take the number 23,882,105 and divide it by 2:
23,882,105 ÷ 2 = 11,941,052.5
If the quotient is a whole number, then 2 and 11,941,052.5 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 | 23,882,105 | |
| -1 | -23,882,105 |
Now, we try dividing 23,882,105 by 3:
23,882,105 ÷ 3 = 7,960,701.6667
If the quotient is a whole number, then 3 and 7,960,701.6667 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 | 23,882,105 | |
| -1 | -23,882,105 |
Let's try dividing by 4:
23,882,105 ÷ 4 = 5,970,526.25
If the quotient is a whole number, then 4 and 5,970,526.25 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 | 23,882,105 | |
| -1 | 23,882,105 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 461 | 797 | 2,305 | 3,985 | 5,993 | 10,361 | 29,965 | 51,805 | 367,417 | 1,837,085 | 4,776,421 | 23,882,105 |
| -1 | -5 | -13 | -65 | -461 | -797 | -2,305 | -3,985 | -5,993 | -10,361 | -29,965 | -51,805 | -367,417 | -1,837,085 | -4,776,421 | -23,882,105 |
