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 252,666,005, 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 | 252,666,005 | |
| -1 | -252,666,005 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 252,666,005.
Example:
1 x 252,666,005 = 252,666,005
and
-1 x -252,666,005 = 252,666,005
Notice both answers equal 252,666,005
With that explanation out of the way, let's continue. Next, we take the number 252,666,005 and divide it by 2:
252,666,005 ÷ 2 = 126,333,002.5
If the quotient is a whole number, then 2 and 126,333,002.5 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 | 252,666,005 | |
| -1 | -252,666,005 |
Now, we try dividing 252,666,005 by 3:
252,666,005 ÷ 3 = 84,222,001.6667
If the quotient is a whole number, then 3 and 84,222,001.6667 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 | 252,666,005 | |
| -1 | -252,666,005 |
Let's try dividing by 4:
252,666,005 ÷ 4 = 63,166,501.25
If the quotient is a whole number, then 4 and 63,166,501.25 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 | 252,666,005 | |
| -1 | 252,666,005 |
If you did it right, you will end up with this table:
| 1 | 5 | 149 | 229 | 745 | 1,145 | 1,481 | 7,405 | 34,121 | 170,605 | 220,669 | 339,149 | 1,103,345 | 1,695,745 | 50,533,201 | 252,666,005 |
| -1 | -5 | -149 | -229 | -745 | -1,145 | -1,481 | -7,405 | -34,121 | -170,605 | -220,669 | -339,149 | -1,103,345 | -1,695,745 | -50,533,201 | -252,666,005 |
