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 303,151,009, 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 | 303,151,009 | |
| -1 | -303,151,009 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 303,151,009.
Example:
1 x 303,151,009 = 303,151,009
and
-1 x -303,151,009 = 303,151,009
Notice both answers equal 303,151,009
With that explanation out of the way, let's continue. Next, we take the number 303,151,009 and divide it by 2:
303,151,009 ÷ 2 = 151,575,504.5
If the quotient is a whole number, then 2 and 151,575,504.5 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 | 303,151,009 | |
| -1 | -303,151,009 |
Now, we try dividing 303,151,009 by 3:
303,151,009 ÷ 3 = 101,050,336.3333
If the quotient is a whole number, then 3 and 101,050,336.3333 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 | 303,151,009 | |
| -1 | -303,151,009 |
Let's try dividing by 4:
303,151,009 ÷ 4 = 75,787,752.25
If the quotient is a whole number, then 4 and 75,787,752.25 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 | 303,151,009 | |
| -1 | 303,151,009 |
If you did it right, you will end up with this table:
| 1 | 7 | 107 | 227 | 749 | 1,589 | 1,783 | 12,481 | 24,289 | 170,023 | 190,781 | 404,741 | 1,335,467 | 2,833,187 | 43,307,287 | 303,151,009 |
| -1 | -7 | -107 | -227 | -749 | -1,589 | -1,783 | -12,481 | -24,289 | -170,023 | -190,781 | -404,741 | -1,335,467 | -2,833,187 | -43,307,287 | -303,151,009 |
