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 3,301,621, 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 | 3,301,621 | |
| -1 | -3,301,621 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,301,621.
Example:
1 x 3,301,621 = 3,301,621
and
-1 x -3,301,621 = 3,301,621
Notice both answers equal 3,301,621
With that explanation out of the way, let's continue. Next, we take the number 3,301,621 and divide it by 2:
3,301,621 ÷ 2 = 1,650,810.5
If the quotient is a whole number, then 2 and 1,650,810.5 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 | 3,301,621 | |
| -1 | -3,301,621 |
Now, we try dividing 3,301,621 by 3:
3,301,621 ÷ 3 = 1,100,540.3333
If the quotient is a whole number, then 3 and 1,100,540.3333 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 | 3,301,621 | |
| -1 | -3,301,621 |
Let's try dividing by 4:
3,301,621 ÷ 4 = 825,405.25
If the quotient is a whole number, then 4 and 825,405.25 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 | 3,301,621 | |
| -1 | 3,301,621 |
If you did it right, you will end up with this table:
| 1 | 17 | 29 | 37 | 181 | 493 | 629 | 1,073 | 3,077 | 5,249 | 6,697 | 18,241 | 89,233 | 113,849 | 194,213 | 3,301,621 |
| -1 | -17 | -29 | -37 | -181 | -493 | -629 | -1,073 | -3,077 | -5,249 | -6,697 | -18,241 | -89,233 | -113,849 | -194,213 | -3,301,621 |
