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 205,033,115, 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 | 205,033,115 | |
| -1 | -205,033,115 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 205,033,115.
Example:
1 x 205,033,115 = 205,033,115
and
-1 x -205,033,115 = 205,033,115
Notice both answers equal 205,033,115
With that explanation out of the way, let's continue. Next, we take the number 205,033,115 and divide it by 2:
205,033,115 ÷ 2 = 102,516,557.5
If the quotient is a whole number, then 2 and 102,516,557.5 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 | 205,033,115 | |
| -1 | -205,033,115 |
Now, we try dividing 205,033,115 by 3:
205,033,115 ÷ 3 = 68,344,371.6667
If the quotient is a whole number, then 3 and 68,344,371.6667 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 | 205,033,115 | |
| -1 | -205,033,115 |
Let's try dividing by 4:
205,033,115 ÷ 4 = 51,258,278.75
If the quotient is a whole number, then 4 and 51,258,278.75 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 | 205,033,115 | |
| -1 | 205,033,115 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 251 | 1,255 | 1,757 | 8,785 | 23,339 | 116,695 | 163,373 | 816,865 | 5,858,089 | 29,290,445 | 41,006,623 | 205,033,115 |
| -1 | -5 | -7 | -35 | -251 | -1,255 | -1,757 | -8,785 | -23,339 | -116,695 | -163,373 | -816,865 | -5,858,089 | -29,290,445 | -41,006,623 | -205,033,115 |
