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 3,301,331, 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 | 3,301,331 | |
| -1 | -3,301,331 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,301,331.
Example:
1 x 3,301,331 = 3,301,331
and
-1 x -3,301,331 = 3,301,331
Notice both answers equal 3,301,331
With that explanation out of the way, let's continue. Next, we take the number 3,301,331 and divide it by 2:
3,301,331 ÷ 2 = 1,650,665.5
If the quotient is a whole number, then 2 and 1,650,665.5 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 | 3,301,331 | |
| -1 | -3,301,331 |
Now, we try dividing 3,301,331 by 3:
3,301,331 ÷ 3 = 1,100,443.6667
If the quotient is a whole number, then 3 and 1,100,443.6667 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 | 3,301,331 | |
| -1 | -3,301,331 |
Let's try dividing by 4:
3,301,331 ÷ 4 = 825,332.75
If the quotient is a whole number, then 4 and 825,332.75 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 | 3,301,331 | |
| -1 | 3,301,331 |
If you did it right, you will end up with this table:
| 1 | 11 | 29 | 79 | 131 | 319 | 869 | 1,441 | 2,291 | 3,799 | 10,349 | 25,201 | 41,789 | 113,839 | 300,121 | 3,301,331 |
| -1 | -11 | -29 | -79 | -131 | -319 | -869 | -1,441 | -2,291 | -3,799 | -10,349 | -25,201 | -41,789 | -113,839 | -300,121 | -3,301,331 |
