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 11,055,355, 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 | 11,055,355 | |
| -1 | -11,055,355 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 11,055,355.
Example:
1 x 11,055,355 = 11,055,355
and
-1 x -11,055,355 = 11,055,355
Notice both answers equal 11,055,355
With that explanation out of the way, let's continue. Next, we take the number 11,055,355 and divide it by 2:
11,055,355 ÷ 2 = 5,527,677.5
If the quotient is a whole number, then 2 and 5,527,677.5 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 | 11,055,355 | |
| -1 | -11,055,355 |
Now, we try dividing 11,055,355 by 3:
11,055,355 ÷ 3 = 3,685,118.3333
If the quotient is a whole number, then 3 and 3,685,118.3333 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 | 11,055,355 | |
| -1 | -11,055,355 |
Let's try dividing by 4:
11,055,355 ÷ 4 = 2,763,838.75
If the quotient is a whole number, then 4 and 2,763,838.75 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 | 11,055,355 | |
| -1 | 11,055,355 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 113 | 565 | 1,151 | 1,921 | 5,755 | 9,605 | 19,567 | 97,835 | 130,063 | 650,315 | 2,211,071 | 11,055,355 |
| -1 | -5 | -17 | -85 | -113 | -565 | -1,151 | -1,921 | -5,755 | -9,605 | -19,567 | -97,835 | -130,063 | -650,315 | -2,211,071 | -11,055,355 |
