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 104,431,315, 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 | 104,431,315 | |
| -1 | -104,431,315 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 104,431,315.
Example:
1 x 104,431,315 = 104,431,315
and
-1 x -104,431,315 = 104,431,315
Notice both answers equal 104,431,315
With that explanation out of the way, let's continue. Next, we take the number 104,431,315 and divide it by 2:
104,431,315 ÷ 2 = 52,215,657.5
If the quotient is a whole number, then 2 and 52,215,657.5 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 | 104,431,315 | |
| -1 | -104,431,315 |
Now, we try dividing 104,431,315 by 3:
104,431,315 ÷ 3 = 34,810,438.3333
If the quotient is a whole number, then 3 and 34,810,438.3333 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 | 104,431,315 | |
| -1 | -104,431,315 |
Let's try dividing by 4:
104,431,315 ÷ 4 = 26,107,828.75
If the quotient is a whole number, then 4 and 26,107,828.75 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 | 104,431,315 | |
| -1 | 104,431,315 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 95 | 607 | 1,811 | 3,035 | 9,055 | 11,533 | 34,409 | 57,665 | 172,045 | 1,099,277 | 5,496,385 | 20,886,263 | 104,431,315 |
| -1 | -5 | -19 | -95 | -607 | -1,811 | -3,035 | -9,055 | -11,533 | -34,409 | -57,665 | -172,045 | -1,099,277 | -5,496,385 | -20,886,263 | -104,431,315 |
