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 252,063,581, 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 | 252,063,581 | |
| -1 | -252,063,581 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 252,063,581.
Example:
1 x 252,063,581 = 252,063,581
and
-1 x -252,063,581 = 252,063,581
Notice both answers equal 252,063,581
With that explanation out of the way, let's continue. Next, we take the number 252,063,581 and divide it by 2:
252,063,581 ÷ 2 = 126,031,790.5
If the quotient is a whole number, then 2 and 126,031,790.5 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 | 252,063,581 | |
| -1 | -252,063,581 |
Now, we try dividing 252,063,581 by 3:
252,063,581 ÷ 3 = 84,021,193.6667
If the quotient is a whole number, then 3 and 84,021,193.6667 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 | 252,063,581 | |
| -1 | -252,063,581 |
Let's try dividing by 4:
252,063,581 ÷ 4 = 63,015,895.25
If the quotient is a whole number, then 4 and 63,015,895.25 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 | 252,063,581 | |
| -1 | 252,063,581 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 67 | 77 | 469 | 737 | 5,159 | 48,859 | 342,013 | 537,449 | 3,273,553 | 3,762,143 | 22,914,871 | 36,009,083 | 252,063,581 |
| -1 | -7 | -11 | -67 | -77 | -469 | -737 | -5,159 | -48,859 | -342,013 | -537,449 | -3,273,553 | -3,762,143 | -22,914,871 | -36,009,083 | -252,063,581 |
