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 100,313,039, 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 | 100,313,039 | |
| -1 | -100,313,039 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 100,313,039.
Example:
1 x 100,313,039 = 100,313,039
and
-1 x -100,313,039 = 100,313,039
Notice both answers equal 100,313,039
With that explanation out of the way, let's continue. Next, we take the number 100,313,039 and divide it by 2:
100,313,039 ÷ 2 = 50,156,519.5
If the quotient is a whole number, then 2 and 50,156,519.5 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 | 100,313,039 | |
| -1 | -100,313,039 |
Now, we try dividing 100,313,039 by 3:
100,313,039 ÷ 3 = 33,437,679.6667
If the quotient is a whole number, then 3 and 33,437,679.6667 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 | 100,313,039 | |
| -1 | -100,313,039 |
Let's try dividing by 4:
100,313,039 ÷ 4 = 25,078,259.75
If the quotient is a whole number, then 4 and 25,078,259.75 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 | 100,313,039 | |
| -1 | 100,313,039 |
If you did it right, you will end up with this table:
| 1 | 17 | 59 | 103 | 971 | 1,003 | 1,751 | 6,077 | 16,507 | 57,289 | 100,013 | 103,309 | 973,913 | 1,700,221 | 5,900,767 | 100,313,039 |
| -1 | -17 | -59 | -103 | -971 | -1,003 | -1,751 | -6,077 | -16,507 | -57,289 | -100,013 | -103,309 | -973,913 | -1,700,221 | -5,900,767 | -100,313,039 |
