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 252,614,453, 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 | 252,614,453 | |
| -1 | -252,614,453 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 252,614,453.
Example:
1 x 252,614,453 = 252,614,453
and
-1 x -252,614,453 = 252,614,453
Notice both answers equal 252,614,453
With that explanation out of the way, let's continue. Next, we take the number 252,614,453 and divide it by 2:
252,614,453 ÷ 2 = 126,307,226.5
If the quotient is a whole number, then 2 and 126,307,226.5 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 | 252,614,453 | |
| -1 | -252,614,453 |
Now, we try dividing 252,614,453 by 3:
252,614,453 ÷ 3 = 84,204,817.6667
If the quotient is a whole number, then 3 and 84,204,817.6667 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 | 252,614,453 | |
| -1 | -252,614,453 |
Let's try dividing by 4:
252,614,453 ÷ 4 = 63,153,613.25
If the quotient is a whole number, then 4 and 63,153,613.25 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 | 252,614,453 | |
| -1 | 252,614,453 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 49 | 91 | 227 | 637 | 1,589 | 1,747 | 2,951 | 11,123 | 12,229 | 20,657 | 22,711 | 85,603 | 144,599 | 158,977 | 396,569 | 1,112,839 | 2,775,983 | 5,155,397 | 19,431,881 | 36,087,779 | 252,614,453 |
| -1 | -7 | -13 | -49 | -91 | -227 | -637 | -1,589 | -1,747 | -2,951 | -11,123 | -12,229 | -20,657 | -22,711 | -85,603 | -144,599 | -158,977 | -396,569 | -1,112,839 | -2,775,983 | -5,155,397 | -19,431,881 | -36,087,779 | -252,614,453 |
