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 5,511,805, 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 | 5,511,805 | |
| -1 | -5,511,805 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,511,805.
Example:
1 x 5,511,805 = 5,511,805
and
-1 x -5,511,805 = 5,511,805
Notice both answers equal 5,511,805
With that explanation out of the way, let's continue. Next, we take the number 5,511,805 and divide it by 2:
5,511,805 ÷ 2 = 2,755,902.5
If the quotient is a whole number, then 2 and 2,755,902.5 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 | 5,511,805 | |
| -1 | -5,511,805 |
Now, we try dividing 5,511,805 by 3:
5,511,805 ÷ 3 = 1,837,268.3333
If the quotient is a whole number, then 3 and 1,837,268.3333 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 | 5,511,805 | |
| -1 | -5,511,805 |
Let's try dividing by 4:
5,511,805 ÷ 4 = 1,377,951.25
If the quotient is a whole number, then 4 and 1,377,951.25 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 | 5,511,805 | |
| -1 | 5,511,805 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 19 | 65 | 95 | 247 | 1,235 | 4,463 | 22,315 | 58,019 | 84,797 | 290,095 | 423,985 | 1,102,361 | 5,511,805 |
| -1 | -5 | -13 | -19 | -65 | -95 | -247 | -1,235 | -4,463 | -22,315 | -58,019 | -84,797 | -290,095 | -423,985 | -1,102,361 | -5,511,805 |
