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 3,320,291, 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 | 3,320,291 | |
| -1 | -3,320,291 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,320,291.
Example:
1 x 3,320,291 = 3,320,291
and
-1 x -3,320,291 = 3,320,291
Notice both answers equal 3,320,291
With that explanation out of the way, let's continue. Next, we take the number 3,320,291 and divide it by 2:
3,320,291 ÷ 2 = 1,660,145.5
If the quotient is a whole number, then 2 and 1,660,145.5 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 | 3,320,291 | |
| -1 | -3,320,291 |
Now, we try dividing 3,320,291 by 3:
3,320,291 ÷ 3 = 1,106,763.6667
If the quotient is a whole number, then 3 and 1,106,763.6667 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 | 3,320,291 | |
| -1 | -3,320,291 |
Let's try dividing by 4:
3,320,291 ÷ 4 = 830,072.75
If the quotient is a whole number, then 4 and 830,072.75 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 | 3,320,291 | |
| -1 | 3,320,291 |
If you did it right, you will end up with this table:
| 1 | 13 | 53 | 61 | 79 | 689 | 793 | 1,027 | 3,233 | 4,187 | 4,819 | 42,029 | 54,431 | 62,647 | 255,407 | 3,320,291 |
| -1 | -13 | -53 | -61 | -79 | -689 | -793 | -1,027 | -3,233 | -4,187 | -4,819 | -42,029 | -54,431 | -62,647 | -255,407 | -3,320,291 |
