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 3,290,665, 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 | 3,290,665 | |
| -1 | -3,290,665 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,290,665.
Example:
1 x 3,290,665 = 3,290,665
and
-1 x -3,290,665 = 3,290,665
Notice both answers equal 3,290,665
With that explanation out of the way, let's continue. Next, we take the number 3,290,665 and divide it by 2:
3,290,665 ÷ 2 = 1,645,332.5
If the quotient is a whole number, then 2 and 1,645,332.5 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 | 3,290,665 | |
| -1 | -3,290,665 |
Now, we try dividing 3,290,665 by 3:
3,290,665 ÷ 3 = 1,096,888.3333
If the quotient is a whole number, then 3 and 1,096,888.3333 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 | 3,290,665 | |
| -1 | -3,290,665 |
Let's try dividing by 4:
3,290,665 ÷ 4 = 822,666.25
If the quotient is a whole number, then 4 and 822,666.25 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 | 3,290,665 | |
| -1 | 3,290,665 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 149 | 631 | 745 | 1,043 | 3,155 | 4,417 | 5,215 | 22,085 | 94,019 | 470,095 | 658,133 | 3,290,665 |
| -1 | -5 | -7 | -35 | -149 | -631 | -745 | -1,043 | -3,155 | -4,417 | -5,215 | -22,085 | -94,019 | -470,095 | -658,133 | -3,290,665 |
