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 2,331,665, 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 | 2,331,665 | |
| -1 | -2,331,665 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,331,665.
Example:
1 x 2,331,665 = 2,331,665
and
-1 x -2,331,665 = 2,331,665
Notice both answers equal 2,331,665
With that explanation out of the way, let's continue. Next, we take the number 2,331,665 and divide it by 2:
2,331,665 ÷ 2 = 1,165,832.5
If the quotient is a whole number, then 2 and 1,165,832.5 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 | 2,331,665 | |
| -1 | -2,331,665 |
Now, we try dividing 2,331,665 by 3:
2,331,665 ÷ 3 = 777,221.6667
If the quotient is a whole number, then 3 and 777,221.6667 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 | 2,331,665 | |
| -1 | -2,331,665 |
Let's try dividing by 4:
2,331,665 ÷ 4 = 582,916.25
If the quotient is a whole number, then 4 and 582,916.25 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 | 2,331,665 | |
| -1 | 2,331,665 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 31 | 35 | 49 | 155 | 217 | 245 | 307 | 1,085 | 1,519 | 1,535 | 2,149 | 7,595 | 9,517 | 10,745 | 15,043 | 47,585 | 66,619 | 75,215 | 333,095 | 466,333 | 2,331,665 |
| -1 | -5 | -7 | -31 | -35 | -49 | -155 | -217 | -245 | -307 | -1,085 | -1,519 | -1,535 | -2,149 | -7,595 | -9,517 | -10,745 | -15,043 | -47,585 | -66,619 | -75,215 | -333,095 | -466,333 | -2,331,665 |
