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 303,551,165, 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 | 303,551,165 | |
| -1 | -303,551,165 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 303,551,165.
Example:
1 x 303,551,165 = 303,551,165
and
-1 x -303,551,165 = 303,551,165
Notice both answers equal 303,551,165
With that explanation out of the way, let's continue. Next, we take the number 303,551,165 and divide it by 2:
303,551,165 ÷ 2 = 151,775,582.5
If the quotient is a whole number, then 2 and 151,775,582.5 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 | 303,551,165 | |
| -1 | -303,551,165 |
Now, we try dividing 303,551,165 by 3:
303,551,165 ÷ 3 = 101,183,721.6667
If the quotient is a whole number, then 3 and 101,183,721.6667 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 | 303,551,165 | |
| -1 | -303,551,165 |
Let's try dividing by 4:
303,551,165 ÷ 4 = 75,887,791.25
If the quotient is a whole number, then 4 and 75,887,791.25 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 | 303,551,165 | |
| -1 | 303,551,165 |
If you did it right, you will end up with this table:
| 1 | 5 | 59 | 271 | 295 | 1,355 | 3,797 | 15,989 | 18,985 | 79,945 | 224,023 | 1,028,987 | 1,120,115 | 5,144,935 | 60,710,233 | 303,551,165 |
| -1 | -5 | -59 | -271 | -295 | -1,355 | -3,797 | -15,989 | -18,985 | -79,945 | -224,023 | -1,028,987 | -1,120,115 | -5,144,935 | -60,710,233 | -303,551,165 |
