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 104,231,131, 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 | 104,231,131 | |
| -1 | -104,231,131 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 104,231,131.
Example:
1 x 104,231,131 = 104,231,131
and
-1 x -104,231,131 = 104,231,131
Notice both answers equal 104,231,131
With that explanation out of the way, let's continue. Next, we take the number 104,231,131 and divide it by 2:
104,231,131 ÷ 2 = 52,115,565.5
If the quotient is a whole number, then 2 and 52,115,565.5 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 | 104,231,131 | |
| -1 | -104,231,131 |
Now, we try dividing 104,231,131 by 3:
104,231,131 ÷ 3 = 34,743,710.3333
If the quotient is a whole number, then 3 and 34,743,710.3333 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 | 104,231,131 | |
| -1 | -104,231,131 |
Let's try dividing by 4:
104,231,131 ÷ 4 = 26,057,782.75
If the quotient is a whole number, then 4 and 26,057,782.75 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 | 104,231,131 | |
| -1 | 104,231,131 |
If you did it right, you will end up with this table:
| 1 | 17 | 19 | 323 | 467 | 691 | 7,939 | 8,873 | 11,747 | 13,129 | 150,841 | 223,193 | 322,697 | 5,485,849 | 6,131,243 | 104,231,131 |
| -1 | -17 | -19 | -323 | -467 | -691 | -7,939 | -8,873 | -11,747 | -13,129 | -150,841 | -223,193 | -322,697 | -5,485,849 | -6,131,243 | -104,231,131 |
