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 204,031,559, 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 | 204,031,559 | |
| -1 | -204,031,559 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 204,031,559.
Example:
1 x 204,031,559 = 204,031,559
and
-1 x -204,031,559 = 204,031,559
Notice both answers equal 204,031,559
With that explanation out of the way, let's continue. Next, we take the number 204,031,559 and divide it by 2:
204,031,559 ÷ 2 = 102,015,779.5
If the quotient is a whole number, then 2 and 102,015,779.5 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 | 204,031,559 | |
| -1 | -204,031,559 |
Now, we try dividing 204,031,559 by 3:
204,031,559 ÷ 3 = 68,010,519.6667
If the quotient is a whole number, then 3 and 68,010,519.6667 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 | 204,031,559 | |
| -1 | -204,031,559 |
Let's try dividing by 4:
204,031,559 ÷ 4 = 51,007,889.75
If the quotient is a whole number, then 4 and 51,007,889.75 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 | 204,031,559 | |
| -1 | 204,031,559 |
If you did it right, you will end up with this table:
| 1 | 29 | 47 | 107 | 1,363 | 1,399 | 3,103 | 5,029 | 40,571 | 65,753 | 145,841 | 149,693 | 1,906,837 | 4,341,097 | 7,035,571 | 204,031,559 |
| -1 | -29 | -47 | -107 | -1,363 | -1,399 | -3,103 | -5,029 | -40,571 | -65,753 | -145,841 | -149,693 | -1,906,837 | -4,341,097 | -7,035,571 | -204,031,559 |
