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 233,031,113, 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 | 233,031,113 | |
| -1 | -233,031,113 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 233,031,113.
Example:
1 x 233,031,113 = 233,031,113
and
-1 x -233,031,113 = 233,031,113
Notice both answers equal 233,031,113
With that explanation out of the way, let's continue. Next, we take the number 233,031,113 and divide it by 2:
233,031,113 ÷ 2 = 116,515,556.5
If the quotient is a whole number, then 2 and 116,515,556.5 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 | 233,031,113 | |
| -1 | -233,031,113 |
Now, we try dividing 233,031,113 by 3:
233,031,113 ÷ 3 = 77,677,037.6667
If the quotient is a whole number, then 3 and 77,677,037.6667 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 | 233,031,113 | |
| -1 | -233,031,113 |
Let's try dividing by 4:
233,031,113 ÷ 4 = 58,257,778.25
If the quotient is a whole number, then 4 and 58,257,778.25 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 | 233,031,113 | |
| -1 | 233,031,113 |
If you did it right, you will end up with this table:
| 1 | 7 | 49 | 307 | 343 | 2,149 | 2,213 | 15,043 | 15,491 | 105,301 | 108,437 | 679,391 | 759,059 | 4,755,737 | 33,290,159 | 233,031,113 |
| -1 | -7 | -49 | -307 | -343 | -2,149 | -2,213 | -15,043 | -15,491 | -105,301 | -108,437 | -679,391 | -759,059 | -4,755,737 | -33,290,159 | -233,031,113 |
