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 3,309,715, 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 | 3,309,715 | |
| -1 | -3,309,715 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,309,715.
Example:
1 x 3,309,715 = 3,309,715
and
-1 x -3,309,715 = 3,309,715
Notice both answers equal 3,309,715
With that explanation out of the way, let's continue. Next, we take the number 3,309,715 and divide it by 2:
3,309,715 ÷ 2 = 1,654,857.5
If the quotient is a whole number, then 2 and 1,654,857.5 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 | 3,309,715 | |
| -1 | -3,309,715 |
Now, we try dividing 3,309,715 by 3:
3,309,715 ÷ 3 = 1,103,238.3333
If the quotient is a whole number, then 3 and 1,103,238.3333 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 | 3,309,715 | |
| -1 | -3,309,715 |
Let's try dividing by 4:
3,309,715 ÷ 4 = 827,428.75
If the quotient is a whole number, then 4 and 827,428.75 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 | 3,309,715 | |
| -1 | 3,309,715 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 131 | 155 | 163 | 655 | 815 | 4,061 | 5,053 | 20,305 | 21,353 | 25,265 | 106,765 | 661,943 | 3,309,715 |
| -1 | -5 | -31 | -131 | -155 | -163 | -655 | -815 | -4,061 | -5,053 | -20,305 | -21,353 | -25,265 | -106,765 | -661,943 | -3,309,715 |
