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 304,051,715, 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 | 304,051,715 | |
| -1 | -304,051,715 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 304,051,715.
Example:
1 x 304,051,715 = 304,051,715
and
-1 x -304,051,715 = 304,051,715
Notice both answers equal 304,051,715
With that explanation out of the way, let's continue. Next, we take the number 304,051,715 and divide it by 2:
304,051,715 ÷ 2 = 152,025,857.5
If the quotient is a whole number, then 2 and 152,025,857.5 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 | 304,051,715 | |
| -1 | -304,051,715 |
Now, we try dividing 304,051,715 by 3:
304,051,715 ÷ 3 = 101,350,571.6667
If the quotient is a whole number, then 3 and 101,350,571.6667 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 | 304,051,715 | |
| -1 | -304,051,715 |
Let's try dividing by 4:
304,051,715 ÷ 4 = 76,012,928.75
If the quotient is a whole number, then 4 and 76,012,928.75 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 | 304,051,715 | |
| -1 | 304,051,715 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 17 | 55 | 85 | 187 | 935 | 325,189 | 1,625,945 | 3,577,079 | 5,528,213 | 17,885,395 | 27,641,065 | 60,810,343 | 304,051,715 |
| -1 | -5 | -11 | -17 | -55 | -85 | -187 | -935 | -325,189 | -1,625,945 | -3,577,079 | -5,528,213 | -17,885,395 | -27,641,065 | -60,810,343 | -304,051,715 |
