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 555,233,231, 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 | 555,233,231 | |
| -1 | -555,233,231 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 555,233,231.
Example:
1 x 555,233,231 = 555,233,231
and
-1 x -555,233,231 = 555,233,231
Notice both answers equal 555,233,231
With that explanation out of the way, let's continue. Next, we take the number 555,233,231 and divide it by 2:
555,233,231 ÷ 2 = 277,616,615.5
If the quotient is a whole number, then 2 and 277,616,615.5 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 | 555,233,231 | |
| -1 | -555,233,231 |
Now, we try dividing 555,233,231 by 3:
555,233,231 ÷ 3 = 185,077,743.6667
If the quotient is a whole number, then 3 and 185,077,743.6667 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 | 555,233,231 | |
| -1 | -555,233,231 |
Let's try dividing by 4:
555,233,231 ÷ 4 = 138,808,307.75
If the quotient is a whole number, then 4 and 138,808,307.75 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 | 555,233,231 | |
| -1 | 555,233,231 |
If you did it right, you will end up with this table:
| 1 | 7 | 47 | 83 | 329 | 581 | 3,901 | 20,333 | 27,307 | 142,331 | 955,651 | 1,687,639 | 6,689,557 | 11,813,473 | 79,319,033 | 555,233,231 |
| -1 | -7 | -47 | -83 | -329 | -581 | -3,901 | -20,333 | -27,307 | -142,331 | -955,651 | -1,687,639 | -6,689,557 | -11,813,473 | -79,319,033 | -555,233,231 |
