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 331,022,009, 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 | 331,022,009 | |
| -1 | -331,022,009 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 331,022,009.
Example:
1 x 331,022,009 = 331,022,009
and
-1 x -331,022,009 = 331,022,009
Notice both answers equal 331,022,009
With that explanation out of the way, let's continue. Next, we take the number 331,022,009 and divide it by 2:
331,022,009 ÷ 2 = 165,511,004.5
If the quotient is a whole number, then 2 and 165,511,004.5 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 | 331,022,009 | |
| -1 | -331,022,009 |
Now, we try dividing 331,022,009 by 3:
331,022,009 ÷ 3 = 110,340,669.6667
If the quotient is a whole number, then 3 and 110,340,669.6667 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 | 331,022,009 | |
| -1 | -331,022,009 |
Let's try dividing by 4:
331,022,009 ÷ 4 = 82,755,502.25
If the quotient is a whole number, then 4 and 82,755,502.25 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 | 331,022,009 | |
| -1 | 331,022,009 |
If you did it right, you will end up with this table:
| 1 | 19 | 67 | 457 | 569 | 1,273 | 8,683 | 10,811 | 30,619 | 38,123 | 260,033 | 581,761 | 724,337 | 4,940,627 | 17,422,211 | 331,022,009 |
| -1 | -19 | -67 | -457 | -569 | -1,273 | -8,683 | -10,811 | -30,619 | -38,123 | -260,033 | -581,761 | -724,337 | -4,940,627 | -17,422,211 | -331,022,009 |
