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 11,861,665, 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 | 11,861,665 | |
| -1 | -11,861,665 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 11,861,665.
Example:
1 x 11,861,665 = 11,861,665
and
-1 x -11,861,665 = 11,861,665
Notice both answers equal 11,861,665
With that explanation out of the way, let's continue. Next, we take the number 11,861,665 and divide it by 2:
11,861,665 ÷ 2 = 5,930,832.5
If the quotient is a whole number, then 2 and 5,930,832.5 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 | 11,861,665 | |
| -1 | -11,861,665 |
Now, we try dividing 11,861,665 by 3:
11,861,665 ÷ 3 = 3,953,888.3333
If the quotient is a whole number, then 3 and 3,953,888.3333 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 | 11,861,665 | |
| -1 | -11,861,665 |
Let's try dividing by 4:
11,861,665 ÷ 4 = 2,965,416.25
If the quotient is a whole number, then 4 and 2,965,416.25 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 | 11,861,665 | |
| -1 | 11,861,665 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 53 | 85 | 265 | 901 | 2,633 | 4,505 | 13,165 | 44,761 | 139,549 | 223,805 | 697,745 | 2,372,333 | 11,861,665 |
| -1 | -5 | -17 | -53 | -85 | -265 | -901 | -2,633 | -4,505 | -13,165 | -44,761 | -139,549 | -223,805 | -697,745 | -2,372,333 | -11,861,665 |
