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 550,453,115, 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 | 550,453,115 | |
| -1 | -550,453,115 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 550,453,115.
Example:
1 x 550,453,115 = 550,453,115
and
-1 x -550,453,115 = 550,453,115
Notice both answers equal 550,453,115
With that explanation out of the way, let's continue. Next, we take the number 550,453,115 and divide it by 2:
550,453,115 ÷ 2 = 275,226,557.5
If the quotient is a whole number, then 2 and 275,226,557.5 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 | 550,453,115 | |
| -1 | -550,453,115 |
Now, we try dividing 550,453,115 by 3:
550,453,115 ÷ 3 = 183,484,371.6667
If the quotient is a whole number, then 3 and 183,484,371.6667 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 | 550,453,115 | |
| -1 | -550,453,115 |
Let's try dividing by 4:
550,453,115 ÷ 4 = 137,613,278.75
If the quotient is a whole number, then 4 and 137,613,278.75 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 | 550,453,115 | |
| -1 | 550,453,115 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 103 | 515 | 1,751 | 8,755 | 62,873 | 314,365 | 1,068,841 | 5,344,205 | 6,475,919 | 32,379,595 | 110,090,623 | 550,453,115 |
| -1 | -5 | -17 | -85 | -103 | -515 | -1,751 | -8,755 | -62,873 | -314,365 | -1,068,841 | -5,344,205 | -6,475,919 | -32,379,595 | -110,090,623 | -550,453,115 |
