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 3,068,585, 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 | 3,068,585 | |
| -1 | -3,068,585 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,068,585.
Example:
1 x 3,068,585 = 3,068,585
and
-1 x -3,068,585 = 3,068,585
Notice both answers equal 3,068,585
With that explanation out of the way, let's continue. Next, we take the number 3,068,585 and divide it by 2:
3,068,585 ÷ 2 = 1,534,292.5
If the quotient is a whole number, then 2 and 1,534,292.5 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 | 3,068,585 | |
| -1 | -3,068,585 |
Now, we try dividing 3,068,585 by 3:
3,068,585 ÷ 3 = 1,022,861.6667
If the quotient is a whole number, then 3 and 1,022,861.6667 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 | 3,068,585 | |
| -1 | -3,068,585 |
Let's try dividing by 4:
3,068,585 ÷ 4 = 767,146.25
If the quotient is a whole number, then 4 and 767,146.25 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 | 3,068,585 | |
| -1 | 3,068,585 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 17 | 65 | 85 | 221 | 1,105 | 2,777 | 13,885 | 36,101 | 47,209 | 180,505 | 236,045 | 613,717 | 3,068,585 |
| -1 | -5 | -13 | -17 | -65 | -85 | -221 | -1,105 | -2,777 | -13,885 | -36,101 | -47,209 | -180,505 | -236,045 | -613,717 | -3,068,585 |
