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 330,221,101, 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 | 330,221,101 | |
| -1 | -330,221,101 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 330,221,101.
Example:
1 x 330,221,101 = 330,221,101
and
-1 x -330,221,101 = 330,221,101
Notice both answers equal 330,221,101
With that explanation out of the way, let's continue. Next, we take the number 330,221,101 and divide it by 2:
330,221,101 ÷ 2 = 165,110,550.5
If the quotient is a whole number, then 2 and 165,110,550.5 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 | 330,221,101 | |
| -1 | -330,221,101 |
Now, we try dividing 330,221,101 by 3:
330,221,101 ÷ 3 = 110,073,700.3333
If the quotient is a whole number, then 3 and 110,073,700.3333 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 | 330,221,101 | |
| -1 | -330,221,101 |
Let's try dividing by 4:
330,221,101 ÷ 4 = 82,555,275.25
If the quotient is a whole number, then 4 and 82,555,275.25 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 | 330,221,101 | |
| -1 | 330,221,101 |
If you did it right, you will end up with this table:
| 1 | 7 | 137 | 149 | 959 | 1,043 | 2,311 | 16,177 | 20,413 | 142,891 | 316,607 | 344,339 | 2,216,249 | 2,410,373 | 47,174,443 | 330,221,101 |
| -1 | -7 | -137 | -149 | -959 | -1,043 | -2,311 | -16,177 | -20,413 | -142,891 | -316,607 | -344,339 | -2,216,249 | -2,410,373 | -47,174,443 | -330,221,101 |
