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 252,588,805, 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 | 252,588,805 | |
| -1 | -252,588,805 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 252,588,805.
Example:
1 x 252,588,805 = 252,588,805
and
-1 x -252,588,805 = 252,588,805
Notice both answers equal 252,588,805
With that explanation out of the way, let's continue. Next, we take the number 252,588,805 and divide it by 2:
252,588,805 ÷ 2 = 126,294,402.5
If the quotient is a whole number, then 2 and 126,294,402.5 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 | 252,588,805 | |
| -1 | -252,588,805 |
Now, we try dividing 252,588,805 by 3:
252,588,805 ÷ 3 = 84,196,268.3333
If the quotient is a whole number, then 3 and 84,196,268.3333 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 | 252,588,805 | |
| -1 | -252,588,805 |
Let's try dividing by 4:
252,588,805 ÷ 4 = 63,147,201.25
If the quotient is a whole number, then 4 and 63,147,201.25 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 | 252,588,805 | |
| -1 | 252,588,805 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 17 | 35 | 85 | 119 | 595 | 424,519 | 2,122,595 | 2,971,633 | 7,216,823 | 14,858,165 | 36,084,115 | 50,517,761 | 252,588,805 |
| -1 | -5 | -7 | -17 | -35 | -85 | -119 | -595 | -424,519 | -2,122,595 | -2,971,633 | -7,216,823 | -14,858,165 | -36,084,115 | -50,517,761 | -252,588,805 |
