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 5,508,155, 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 | 5,508,155 | |
| -1 | -5,508,155 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,508,155.
Example:
1 x 5,508,155 = 5,508,155
and
-1 x -5,508,155 = 5,508,155
Notice both answers equal 5,508,155
With that explanation out of the way, let's continue. Next, we take the number 5,508,155 and divide it by 2:
5,508,155 ÷ 2 = 2,754,077.5
If the quotient is a whole number, then 2 and 2,754,077.5 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 | 5,508,155 | |
| -1 | -5,508,155 |
Now, we try dividing 5,508,155 by 3:
5,508,155 ÷ 3 = 1,836,051.6667
If the quotient is a whole number, then 3 and 1,836,051.6667 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 | 5,508,155 | |
| -1 | -5,508,155 |
Let's try dividing by 4:
5,508,155 ÷ 4 = 1,377,038.75
If the quotient is a whole number, then 4 and 1,377,038.75 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 | 5,508,155 | |
| -1 | 5,508,155 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 115 | 211 | 227 | 1,055 | 1,135 | 4,853 | 5,221 | 24,265 | 26,105 | 47,897 | 239,485 | 1,101,631 | 5,508,155 |
| -1 | -5 | -23 | -115 | -211 | -227 | -1,055 | -1,135 | -4,853 | -5,221 | -24,265 | -26,105 | -47,897 | -239,485 | -1,101,631 | -5,508,155 |
