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 233,020,207, 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 | 233,020,207 | |
| -1 | -233,020,207 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 233,020,207.
Example:
1 x 233,020,207 = 233,020,207
and
-1 x -233,020,207 = 233,020,207
Notice both answers equal 233,020,207
With that explanation out of the way, let's continue. Next, we take the number 233,020,207 and divide it by 2:
233,020,207 ÷ 2 = 116,510,103.5
If the quotient is a whole number, then 2 and 116,510,103.5 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 | 233,020,207 | |
| -1 | -233,020,207 |
Now, we try dividing 233,020,207 by 3:
233,020,207 ÷ 3 = 77,673,402.3333
If the quotient is a whole number, then 3 and 77,673,402.3333 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 | 233,020,207 | |
| -1 | -233,020,207 |
Let's try dividing by 4:
233,020,207 ÷ 4 = 58,255,051.75
If the quotient is a whole number, then 4 and 58,255,051.75 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 | 233,020,207 | |
| -1 | 233,020,207 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 119 | 1,217 | 1,609 | 8,519 | 11,263 | 20,689 | 27,353 | 144,823 | 191,471 | 1,958,153 | 13,707,071 | 33,288,601 | 233,020,207 |
| -1 | -7 | -17 | -119 | -1,217 | -1,609 | -8,519 | -11,263 | -20,689 | -27,353 | -144,823 | -191,471 | -1,958,153 | -13,707,071 | -33,288,601 | -233,020,207 |
