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 252,624,335, 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 | 252,624,335 | |
| -1 | -252,624,335 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 252,624,335.
Example:
1 x 252,624,335 = 252,624,335
and
-1 x -252,624,335 = 252,624,335
Notice both answers equal 252,624,335
With that explanation out of the way, let's continue. Next, we take the number 252,624,335 and divide it by 2:
252,624,335 ÷ 2 = 126,312,167.5
If the quotient is a whole number, then 2 and 126,312,167.5 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 | 252,624,335 | |
| -1 | -252,624,335 |
Now, we try dividing 252,624,335 by 3:
252,624,335 ÷ 3 = 84,208,111.6667
If the quotient is a whole number, then 3 and 84,208,111.6667 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 | 252,624,335 | |
| -1 | -252,624,335 |
Let's try dividing by 4:
252,624,335 ÷ 4 = 63,156,083.75
If the quotient is a whole number, then 4 and 63,156,083.75 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 | 252,624,335 | |
| -1 | 252,624,335 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 509 | 2,545 | 5,839 | 8,653 | 29,195 | 43,265 | 99,263 | 496,315 | 2,972,051 | 14,860,255 | 50,524,867 | 252,624,335 |
| -1 | -5 | -17 | -85 | -509 | -2,545 | -5,839 | -8,653 | -29,195 | -43,265 | -99,263 | -496,315 | -2,972,051 | -14,860,255 | -50,524,867 | -252,624,335 |
