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 100,588,255, 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 | 100,588,255 | |
| -1 | -100,588,255 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 100,588,255.
Example:
1 x 100,588,255 = 100,588,255
and
-1 x -100,588,255 = 100,588,255
Notice both answers equal 100,588,255
With that explanation out of the way, let's continue. Next, we take the number 100,588,255 and divide it by 2:
100,588,255 ÷ 2 = 50,294,127.5
If the quotient is a whole number, then 2 and 50,294,127.5 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 | 100,588,255 | |
| -1 | -100,588,255 |
Now, we try dividing 100,588,255 by 3:
100,588,255 ÷ 3 = 33,529,418.3333
If the quotient is a whole number, then 3 and 33,529,418.3333 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 | 100,588,255 | |
| -1 | -100,588,255 |
Let's try dividing by 4:
100,588,255 ÷ 4 = 25,147,063.75
If the quotient is a whole number, then 4 and 25,147,063.75 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 | 100,588,255 | |
| -1 | 100,588,255 |
If you did it right, you will end up with this table:
| 1 | 5 | 103 | 173 | 515 | 865 | 1,129 | 5,645 | 17,819 | 89,095 | 116,287 | 195,317 | 581,435 | 976,585 | 20,117,651 | 100,588,255 |
| -1 | -5 | -103 | -173 | -515 | -865 | -1,129 | -5,645 | -17,819 | -89,095 | -116,287 | -195,317 | -581,435 | -976,585 | -20,117,651 | -100,588,255 |
