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 252,244,105, 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 | 252,244,105 | |
| -1 | -252,244,105 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 252,244,105.
Example:
1 x 252,244,105 = 252,244,105
and
-1 x -252,244,105 = 252,244,105
Notice both answers equal 252,244,105
With that explanation out of the way, let's continue. Next, we take the number 252,244,105 and divide it by 2:
252,244,105 ÷ 2 = 126,122,052.5
If the quotient is a whole number, then 2 and 126,122,052.5 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 | 252,244,105 | |
| -1 | -252,244,105 |
Now, we try dividing 252,244,105 by 3:
252,244,105 ÷ 3 = 84,081,368.3333
If the quotient is a whole number, then 3 and 84,081,368.3333 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 | 252,244,105 | |
| -1 | -252,244,105 |
Let's try dividing by 4:
252,244,105 ÷ 4 = 63,061,026.25
If the quotient is a whole number, then 4 and 63,061,026.25 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 | 252,244,105 | |
| -1 | 252,244,105 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 115 | 653 | 3,265 | 3,359 | 15,019 | 16,795 | 75,095 | 77,257 | 386,285 | 2,193,427 | 10,967,135 | 50,448,821 | 252,244,105 |
| -1 | -5 | -23 | -115 | -653 | -3,265 | -3,359 | -15,019 | -16,795 | -75,095 | -77,257 | -386,285 | -2,193,427 | -10,967,135 | -50,448,821 | -252,244,105 |
