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 252,435,755, 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 | 252,435,755 | |
| -1 | -252,435,755 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 252,435,755.
Example:
1 x 252,435,755 = 252,435,755
and
-1 x -252,435,755 = 252,435,755
Notice both answers equal 252,435,755
With that explanation out of the way, let's continue. Next, we take the number 252,435,755 and divide it by 2:
252,435,755 ÷ 2 = 126,217,877.5
If the quotient is a whole number, then 2 and 126,217,877.5 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 | 252,435,755 | |
| -1 | -252,435,755 |
Now, we try dividing 252,435,755 by 3:
252,435,755 ÷ 3 = 84,145,251.6667
If the quotient is a whole number, then 3 and 84,145,251.6667 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 | 252,435,755 | |
| -1 | -252,435,755 |
Let's try dividing by 4:
252,435,755 ÷ 4 = 63,108,938.75
If the quotient is a whole number, then 4 and 63,108,938.75 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 | 252,435,755 | |
| -1 | 252,435,755 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 13 | 55 | 65 | 143 | 715 | 353,057 | 1,765,285 | 3,883,627 | 4,589,741 | 19,418,135 | 22,948,705 | 50,487,151 | 252,435,755 |
| -1 | -5 | -11 | -13 | -55 | -65 | -143 | -715 | -353,057 | -1,765,285 | -3,883,627 | -4,589,741 | -19,418,135 | -22,948,705 | -50,487,151 | -252,435,755 |
