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 3,280,109, 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 | 3,280,109 | |
| -1 | -3,280,109 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,280,109.
Example:
1 x 3,280,109 = 3,280,109
and
-1 x -3,280,109 = 3,280,109
Notice both answers equal 3,280,109
With that explanation out of the way, let's continue. Next, we take the number 3,280,109 and divide it by 2:
3,280,109 ÷ 2 = 1,640,054.5
If the quotient is a whole number, then 2 and 1,640,054.5 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 | 3,280,109 | |
| -1 | -3,280,109 |
Now, we try dividing 3,280,109 by 3:
3,280,109 ÷ 3 = 1,093,369.6667
If the quotient is a whole number, then 3 and 1,093,369.6667 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 | 3,280,109 | |
| -1 | -3,280,109 |
Let's try dividing by 4:
3,280,109 ÷ 4 = 820,027.25
If the quotient is a whole number, then 4 and 820,027.25 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 | 3,280,109 | |
| -1 | 3,280,109 |
If you did it right, you will end up with this table:
| 1 | 7 | 49 | 73 | 131 | 343 | 511 | 917 | 3,577 | 6,419 | 9,563 | 25,039 | 44,933 | 66,941 | 468,587 | 3,280,109 |
| -1 | -7 | -49 | -73 | -131 | -343 | -511 | -917 | -3,577 | -6,419 | -9,563 | -25,039 | -44,933 | -66,941 | -468,587 | -3,280,109 |
