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 255,101,573, 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 | 255,101,573 | |
| -1 | -255,101,573 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 255,101,573.
Example:
1 x 255,101,573 = 255,101,573
and
-1 x -255,101,573 = 255,101,573
Notice both answers equal 255,101,573
With that explanation out of the way, let's continue. Next, we take the number 255,101,573 and divide it by 2:
255,101,573 ÷ 2 = 127,550,786.5
If the quotient is a whole number, then 2 and 127,550,786.5 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 | 255,101,573 | |
| -1 | -255,101,573 |
Now, we try dividing 255,101,573 by 3:
255,101,573 ÷ 3 = 85,033,857.6667
If the quotient is a whole number, then 3 and 85,033,857.6667 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 | 255,101,573 | |
| -1 | -255,101,573 |
Let's try dividing by 4:
255,101,573 ÷ 4 = 63,775,393.25
If the quotient is a whole number, then 4 and 63,775,393.25 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 | 255,101,573 | |
| -1 | 255,101,573 |
If you did it right, you will end up with this table:
| 1 | 31 | 61 | 313 | 431 | 1,891 | 9,703 | 13,361 | 19,093 | 26,291 | 134,903 | 591,883 | 815,021 | 4,181,993 | 8,229,083 | 255,101,573 |
| -1 | -31 | -61 | -313 | -431 | -1,891 | -9,703 | -13,361 | -19,093 | -26,291 | -134,903 | -591,883 | -815,021 | -4,181,993 | -8,229,083 | -255,101,573 |
