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 3,280,459, 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 | 3,280,459 | |
| -1 | -3,280,459 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,280,459.
Example:
1 x 3,280,459 = 3,280,459
and
-1 x -3,280,459 = 3,280,459
Notice both answers equal 3,280,459
With that explanation out of the way, let's continue. Next, we take the number 3,280,459 and divide it by 2:
3,280,459 ÷ 2 = 1,640,229.5
If the quotient is a whole number, then 2 and 1,640,229.5 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 | 3,280,459 | |
| -1 | -3,280,459 |
Now, we try dividing 3,280,459 by 3:
3,280,459 ÷ 3 = 1,093,486.3333
If the quotient is a whole number, then 3 and 1,093,486.3333 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 | 3,280,459 | |
| -1 | -3,280,459 |
Let's try dividing by 4:
3,280,459 ÷ 4 = 820,114.75
If the quotient is a whole number, then 4 and 820,114.75 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 | 3,280,459 | |
| -1 | 3,280,459 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 47 | 59 | 91 | 169 | 329 | 413 | 611 | 767 | 1,183 | 2,773 | 4,277 | 5,369 | 7,943 | 9,971 | 19,411 | 36,049 | 55,601 | 69,797 | 252,343 | 468,637 | 3,280,459 |
| -1 | -7 | -13 | -47 | -59 | -91 | -169 | -329 | -413 | -611 | -767 | -1,183 | -2,773 | -4,277 | -5,369 | -7,943 | -9,971 | -19,411 | -36,049 | -55,601 | -69,797 | -252,343 | -468,637 | -3,280,459 |
