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 3,206,005, 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 | 3,206,005 | |
| -1 | -3,206,005 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,206,005.
Example:
1 x 3,206,005 = 3,206,005
and
-1 x -3,206,005 = 3,206,005
Notice both answers equal 3,206,005
With that explanation out of the way, let's continue. Next, we take the number 3,206,005 and divide it by 2:
3,206,005 ÷ 2 = 1,603,002.5
If the quotient is a whole number, then 2 and 1,603,002.5 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 | 3,206,005 | |
| -1 | -3,206,005 |
Now, we try dividing 3,206,005 by 3:
3,206,005 ÷ 3 = 1,068,668.3333
If the quotient is a whole number, then 3 and 1,068,668.3333 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 | 3,206,005 | |
| -1 | -3,206,005 |
Let's try dividing by 4:
3,206,005 ÷ 4 = 801,501.25
If the quotient is a whole number, then 4 and 801,501.25 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 | 3,206,005 | |
| -1 | 3,206,005 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 71 | 355 | 781 | 821 | 3,905 | 4,105 | 9,031 | 45,155 | 58,291 | 291,455 | 641,201 | 3,206,005 |
| -1 | -5 | -11 | -55 | -71 | -355 | -781 | -821 | -3,905 | -4,105 | -9,031 | -45,155 | -58,291 | -291,455 | -641,201 | -3,206,005 |
