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 233,231,305, 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 | 233,231,305 | |
| -1 | -233,231,305 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 233,231,305.
Example:
1 x 233,231,305 = 233,231,305
and
-1 x -233,231,305 = 233,231,305
Notice both answers equal 233,231,305
With that explanation out of the way, let's continue. Next, we take the number 233,231,305 and divide it by 2:
233,231,305 ÷ 2 = 116,615,652.5
If the quotient is a whole number, then 2 and 116,615,652.5 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 | 233,231,305 | |
| -1 | -233,231,305 |
Now, we try dividing 233,231,305 by 3:
233,231,305 ÷ 3 = 77,743,768.3333
If the quotient is a whole number, then 3 and 77,743,768.3333 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 | 233,231,305 | |
| -1 | -233,231,305 |
Let's try dividing by 4:
233,231,305 ÷ 4 = 58,307,826.25
If the quotient is a whole number, then 4 and 58,307,826.25 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 | 233,231,305 | |
| -1 | 233,231,305 |
If you did it right, you will end up with this table:
| 1 | 5 | 79 | 373 | 395 | 1,583 | 1,865 | 7,915 | 29,467 | 125,057 | 147,335 | 590,459 | 625,285 | 2,952,295 | 46,646,261 | 233,231,305 |
| -1 | -5 | -79 | -373 | -395 | -1,583 | -1,865 | -7,915 | -29,467 | -125,057 | -147,335 | -590,459 | -625,285 | -2,952,295 | -46,646,261 | -233,231,305 |
