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 11,836,855, 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 | 11,836,855 | |
| -1 | -11,836,855 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 11,836,855.
Example:
1 x 11,836,855 = 11,836,855
and
-1 x -11,836,855 = 11,836,855
Notice both answers equal 11,836,855
With that explanation out of the way, let's continue. Next, we take the number 11,836,855 and divide it by 2:
11,836,855 ÷ 2 = 5,918,427.5
If the quotient is a whole number, then 2 and 5,918,427.5 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 | 11,836,855 | |
| -1 | -11,836,855 |
Now, we try dividing 11,836,855 by 3:
11,836,855 ÷ 3 = 3,945,618.3333
If the quotient is a whole number, then 3 and 3,945,618.3333 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 | 11,836,855 | |
| -1 | -11,836,855 |
Let's try dividing by 4:
11,836,855 ÷ 4 = 2,959,213.75
If the quotient is a whole number, then 4 and 2,959,213.75 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 | 11,836,855 | |
| -1 | 11,836,855 |
If you did it right, you will end up with this table:
| 1 | 5 | 37 | 109 | 185 | 545 | 587 | 2,935 | 4,033 | 20,165 | 21,719 | 63,983 | 108,595 | 319,915 | 2,367,371 | 11,836,855 |
| -1 | -5 | -37 | -109 | -185 | -545 | -587 | -2,935 | -4,033 | -20,165 | -21,719 | -63,983 | -108,595 | -319,915 | -2,367,371 | -11,836,855 |
