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 3,040,715, 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 | 3,040,715 | |
| -1 | -3,040,715 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,040,715.
Example:
1 x 3,040,715 = 3,040,715
and
-1 x -3,040,715 = 3,040,715
Notice both answers equal 3,040,715
With that explanation out of the way, let's continue. Next, we take the number 3,040,715 and divide it by 2:
3,040,715 ÷ 2 = 1,520,357.5
If the quotient is a whole number, then 2 and 1,520,357.5 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 | 3,040,715 | |
| -1 | -3,040,715 |
Now, we try dividing 3,040,715 by 3:
3,040,715 ÷ 3 = 1,013,571.6667
If the quotient is a whole number, then 3 and 1,013,571.6667 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 | 3,040,715 | |
| -1 | -3,040,715 |
Let's try dividing by 4:
3,040,715 ÷ 4 = 760,178.75
If the quotient is a whole number, then 4 and 760,178.75 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 | 3,040,715 | |
| -1 | 3,040,715 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 115 | 137 | 193 | 685 | 965 | 3,151 | 4,439 | 15,755 | 22,195 | 26,441 | 132,205 | 608,143 | 3,040,715 |
| -1 | -5 | -23 | -115 | -137 | -193 | -685 | -965 | -3,151 | -4,439 | -15,755 | -22,195 | -26,441 | -132,205 | -608,143 | -3,040,715 |
