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 333,321,131, 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 | 333,321,131 | |
| -1 | -333,321,131 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 333,321,131.
Example:
1 x 333,321,131 = 333,321,131
and
-1 x -333,321,131 = 333,321,131
Notice both answers equal 333,321,131
With that explanation out of the way, let's continue. Next, we take the number 333,321,131 and divide it by 2:
333,321,131 ÷ 2 = 166,660,565.5
If the quotient is a whole number, then 2 and 166,660,565.5 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 | 333,321,131 | |
| -1 | -333,321,131 |
Now, we try dividing 333,321,131 by 3:
333,321,131 ÷ 3 = 111,107,043.6667
If the quotient is a whole number, then 3 and 111,107,043.6667 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 | 333,321,131 | |
| -1 | -333,321,131 |
Let's try dividing by 4:
333,321,131 ÷ 4 = 83,330,282.75
If the quotient is a whole number, then 4 and 83,330,282.75 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 | 333,321,131 | |
| -1 | 333,321,131 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 143 | 211 | 2,321 | 2,743 | 11,047 | 30,173 | 121,517 | 143,611 | 1,579,721 | 2,330,917 | 25,640,087 | 30,301,921 | 333,321,131 |
| -1 | -11 | -13 | -143 | -211 | -2,321 | -2,743 | -11,047 | -30,173 | -121,517 | -143,611 | -1,579,721 | -2,330,917 | -25,640,087 | -30,301,921 | -333,321,131 |
