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 330,421,433, 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 | 330,421,433 | |
| -1 | -330,421,433 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 330,421,433.
Example:
1 x 330,421,433 = 330,421,433
and
-1 x -330,421,433 = 330,421,433
Notice both answers equal 330,421,433
With that explanation out of the way, let's continue. Next, we take the number 330,421,433 and divide it by 2:
330,421,433 ÷ 2 = 165,210,716.5
If the quotient is a whole number, then 2 and 165,210,716.5 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 | 330,421,433 | |
| -1 | -330,421,433 |
Now, we try dividing 330,421,433 by 3:
330,421,433 ÷ 3 = 110,140,477.6667
If the quotient is a whole number, then 3 and 110,140,477.6667 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 | 330,421,433 | |
| -1 | -330,421,433 |
Let's try dividing by 4:
330,421,433 ÷ 4 = 82,605,358.25
If the quotient is a whole number, then 4 and 82,605,358.25 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 | 330,421,433 | |
| -1 | 330,421,433 |
If you did it right, you will end up with this table:
| 1 | 37 | 71 | 73 | 1,723 | 2,627 | 2,701 | 5,183 | 63,751 | 122,333 | 125,779 | 191,771 | 4,526,321 | 4,653,823 | 8,930,309 | 330,421,433 |
| -1 | -37 | -71 | -73 | -1,723 | -2,627 | -2,701 | -5,183 | -63,751 | -122,333 | -125,779 | -191,771 | -4,526,321 | -4,653,823 | -8,930,309 | -330,421,433 |
