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 555,153,245, 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 | 555,153,245 | |
| -1 | -555,153,245 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 555,153,245.
Example:
1 x 555,153,245 = 555,153,245
and
-1 x -555,153,245 = 555,153,245
Notice both answers equal 555,153,245
With that explanation out of the way, let's continue. Next, we take the number 555,153,245 and divide it by 2:
555,153,245 ÷ 2 = 277,576,622.5
If the quotient is a whole number, then 2 and 277,576,622.5 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 | 555,153,245 | |
| -1 | -555,153,245 |
Now, we try dividing 555,153,245 by 3:
555,153,245 ÷ 3 = 185,051,081.6667
If the quotient is a whole number, then 3 and 185,051,081.6667 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 | 555,153,245 | |
| -1 | -555,153,245 |
Let's try dividing by 4:
555,153,245 ÷ 4 = 138,788,311.25
If the quotient is a whole number, then 4 and 138,788,311.25 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 | 555,153,245 | |
| -1 | 555,153,245 |
If you did it right, you will end up with this table:
| 1 | 5 | 181 | 619 | 905 | 991 | 3,095 | 4,955 | 112,039 | 179,371 | 560,195 | 613,429 | 896,855 | 3,067,145 | 111,030,649 | 555,153,245 |
| -1 | -5 | -181 | -619 | -905 | -991 | -3,095 | -4,955 | -112,039 | -179,371 | -560,195 | -613,429 | -896,855 | -3,067,145 | -111,030,649 | -555,153,245 |
