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 5,555,809, 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 | 5,555,809 | |
| -1 | -5,555,809 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,555,809.
Example:
1 x 5,555,809 = 5,555,809
and
-1 x -5,555,809 = 5,555,809
Notice both answers equal 5,555,809
With that explanation out of the way, let's continue. Next, we take the number 5,555,809 and divide it by 2:
5,555,809 ÷ 2 = 2,777,904.5
If the quotient is a whole number, then 2 and 2,777,904.5 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 | 5,555,809 | |
| -1 | -5,555,809 |
Now, we try dividing 5,555,809 by 3:
5,555,809 ÷ 3 = 1,851,936.3333
If the quotient is a whole number, then 3 and 1,851,936.3333 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 | 5,555,809 | |
| -1 | -5,555,809 |
Let's try dividing by 4:
5,555,809 ÷ 4 = 1,388,952.25
If the quotient is a whole number, then 4 and 1,388,952.25 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 | 5,555,809 | |
| -1 | 5,555,809 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 37 | 133 | 259 | 703 | 1,129 | 4,921 | 7,903 | 21,451 | 41,773 | 150,157 | 292,411 | 793,687 | 5,555,809 |
| -1 | -7 | -19 | -37 | -133 | -259 | -703 | -1,129 | -4,921 | -7,903 | -21,451 | -41,773 | -150,157 | -292,411 | -793,687 | -5,555,809 |
