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 330,033,011, 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 | 330,033,011 | |
| -1 | -330,033,011 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 330,033,011.
Example:
1 x 330,033,011 = 330,033,011
and
-1 x -330,033,011 = 330,033,011
Notice both answers equal 330,033,011
With that explanation out of the way, let's continue. Next, we take the number 330,033,011 and divide it by 2:
330,033,011 ÷ 2 = 165,016,505.5
If the quotient is a whole number, then 2 and 165,016,505.5 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 | 330,033,011 | |
| -1 | -330,033,011 |
Now, we try dividing 330,033,011 by 3:
330,033,011 ÷ 3 = 110,011,003.6667
If the quotient is a whole number, then 3 and 110,011,003.6667 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 | 330,033,011 | |
| -1 | -330,033,011 |
Let's try dividing by 4:
330,033,011 ÷ 4 = 82,508,252.75
If the quotient is a whole number, then 4 and 82,508,252.75 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 | 330,033,011 | |
| -1 | 330,033,011 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 373 | 2,611 | 4,103 | 11,491 | 28,721 | 80,437 | 126,401 | 884,807 | 4,286,143 | 30,003,001 | 47,147,573 | 330,033,011 |
| -1 | -7 | -11 | -77 | -373 | -2,611 | -4,103 | -11,491 | -28,721 | -80,437 | -126,401 | -884,807 | -4,286,143 | -30,003,001 | -47,147,573 | -330,033,011 |
