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 303,123,515, 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 | 303,123,515 | |
| -1 | -303,123,515 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 303,123,515.
Example:
1 x 303,123,515 = 303,123,515
and
-1 x -303,123,515 = 303,123,515
Notice both answers equal 303,123,515
With that explanation out of the way, let's continue. Next, we take the number 303,123,515 and divide it by 2:
303,123,515 ÷ 2 = 151,561,757.5
If the quotient is a whole number, then 2 and 151,561,757.5 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 | 303,123,515 | |
| -1 | -303,123,515 |
Now, we try dividing 303,123,515 by 3:
303,123,515 ÷ 3 = 101,041,171.6667
If the quotient is a whole number, then 3 and 101,041,171.6667 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 | 303,123,515 | |
| -1 | -303,123,515 |
Let's try dividing by 4:
303,123,515 ÷ 4 = 75,780,878.75
If the quotient is a whole number, then 4 and 75,780,878.75 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 | 303,123,515 | |
| -1 | 303,123,515 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 29 | 85 | 145 | 493 | 2,465 | 122,971 | 614,855 | 2,090,507 | 3,566,159 | 10,452,535 | 17,830,795 | 60,624,703 | 303,123,515 |
| -1 | -5 | -17 | -29 | -85 | -145 | -493 | -2,465 | -122,971 | -614,855 | -2,090,507 | -3,566,159 | -10,452,535 | -17,830,795 | -60,624,703 | -303,123,515 |
