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 205,526,633, 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 | 205,526,633 | |
| -1 | -205,526,633 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 205,526,633.
Example:
1 x 205,526,633 = 205,526,633
and
-1 x -205,526,633 = 205,526,633
Notice both answers equal 205,526,633
With that explanation out of the way, let's continue. Next, we take the number 205,526,633 and divide it by 2:
205,526,633 ÷ 2 = 102,763,316.5
If the quotient is a whole number, then 2 and 102,763,316.5 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 | 205,526,633 | |
| -1 | -205,526,633 |
Now, we try dividing 205,526,633 by 3:
205,526,633 ÷ 3 = 68,508,877.6667
If the quotient is a whole number, then 3 and 68,508,877.6667 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 | 205,526,633 | |
| -1 | -205,526,633 |
Let's try dividing by 4:
205,526,633 ÷ 4 = 51,381,658.25
If the quotient is a whole number, then 4 and 51,381,658.25 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 | 205,526,633 | |
| -1 | 205,526,633 |
If you did it right, you will end up with this table:
| 1 | 13 | 53 | 317 | 689 | 941 | 4,121 | 12,233 | 16,801 | 49,873 | 218,413 | 298,297 | 648,349 | 3,877,861 | 15,809,741 | 205,526,633 |
| -1 | -13 | -53 | -317 | -689 | -941 | -4,121 | -12,233 | -16,801 | -49,873 | -218,413 | -298,297 | -648,349 | -3,877,861 | -15,809,741 | -205,526,633 |
