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 233,221,205, 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 | 233,221,205 | |
| -1 | -233,221,205 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 233,221,205.
Example:
1 x 233,221,205 = 233,221,205
and
-1 x -233,221,205 = 233,221,205
Notice both answers equal 233,221,205
With that explanation out of the way, let's continue. Next, we take the number 233,221,205 and divide it by 2:
233,221,205 ÷ 2 = 116,610,602.5
If the quotient is a whole number, then 2 and 116,610,602.5 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 | 233,221,205 | |
| -1 | -233,221,205 |
Now, we try dividing 233,221,205 by 3:
233,221,205 ÷ 3 = 77,740,401.6667
If the quotient is a whole number, then 3 and 77,740,401.6667 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 | 233,221,205 | |
| -1 | -233,221,205 |
Let's try dividing by 4:
233,221,205 ÷ 4 = 58,305,301.25
If the quotient is a whole number, then 4 and 58,305,301.25 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 | 233,221,205 | |
| -1 | 233,221,205 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 223 | 1,115 | 1,561 | 7,805 | 29,881 | 149,405 | 209,167 | 1,045,835 | 6,663,463 | 33,317,315 | 46,644,241 | 233,221,205 |
| -1 | -5 | -7 | -35 | -223 | -1,115 | -1,561 | -7,805 | -29,881 | -149,405 | -209,167 | -1,045,835 | -6,663,463 | -33,317,315 | -46,644,241 | -233,221,205 |
