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 330,131,137, 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 | 330,131,137 | |
| -1 | -330,131,137 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 330,131,137.
Example:
1 x 330,131,137 = 330,131,137
and
-1 x -330,131,137 = 330,131,137
Notice both answers equal 330,131,137
With that explanation out of the way, let's continue. Next, we take the number 330,131,137 and divide it by 2:
330,131,137 ÷ 2 = 165,065,568.5
If the quotient is a whole number, then 2 and 165,065,568.5 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 | 330,131,137 | |
| -1 | -330,131,137 |
Now, we try dividing 330,131,137 by 3:
330,131,137 ÷ 3 = 110,043,712.3333
If the quotient is a whole number, then 3 and 110,043,712.3333 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 | 330,131,137 | |
| -1 | -330,131,137 |
Let's try dividing by 4:
330,131,137 ÷ 4 = 82,532,784.25
If the quotient is a whole number, then 4 and 82,532,784.25 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 | 330,131,137 | |
| -1 | 330,131,137 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 59 | 133 | 413 | 1,121 | 7,847 | 42,071 | 294,497 | 799,349 | 2,482,189 | 5,595,443 | 17,375,323 | 47,161,591 | 330,131,137 |
| -1 | -7 | -19 | -59 | -133 | -413 | -1,121 | -7,847 | -42,071 | -294,497 | -799,349 | -2,482,189 | -5,595,443 | -17,375,323 | -47,161,591 | -330,131,137 |
