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 23,431,595, 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 | 23,431,595 | |
| -1 | -23,431,595 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,431,595.
Example:
1 x 23,431,595 = 23,431,595
and
-1 x -23,431,595 = 23,431,595
Notice both answers equal 23,431,595
With that explanation out of the way, let's continue. Next, we take the number 23,431,595 and divide it by 2:
23,431,595 ÷ 2 = 11,715,797.5
If the quotient is a whole number, then 2 and 11,715,797.5 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 | 23,431,595 | |
| -1 | -23,431,595 |
Now, we try dividing 23,431,595 by 3:
23,431,595 ÷ 3 = 7,810,531.6667
If the quotient is a whole number, then 3 and 7,810,531.6667 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 | 23,431,595 | |
| -1 | -23,431,595 |
Let's try dividing by 4:
23,431,595 ÷ 4 = 5,857,898.75
If the quotient is a whole number, then 4 and 5,857,898.75 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 | 23,431,595 | |
| -1 | 23,431,595 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 23 | 55 | 115 | 253 | 1,265 | 18,523 | 92,615 | 203,753 | 426,029 | 1,018,765 | 2,130,145 | 4,686,319 | 23,431,595 |
| -1 | -5 | -11 | -23 | -55 | -115 | -253 | -1,265 | -18,523 | -92,615 | -203,753 | -426,029 | -1,018,765 | -2,130,145 | -4,686,319 | -23,431,595 |
