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 331,021,339, 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 | 331,021,339 | |
| -1 | -331,021,339 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 331,021,339.
Example:
1 x 331,021,339 = 331,021,339
and
-1 x -331,021,339 = 331,021,339
Notice both answers equal 331,021,339
With that explanation out of the way, let's continue. Next, we take the number 331,021,339 and divide it by 2:
331,021,339 ÷ 2 = 165,510,669.5
If the quotient is a whole number, then 2 and 165,510,669.5 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 | 331,021,339 | |
| -1 | -331,021,339 |
Now, we try dividing 331,021,339 by 3:
331,021,339 ÷ 3 = 110,340,446.3333
If the quotient is a whole number, then 3 and 110,340,446.3333 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 | 331,021,339 | |
| -1 | -331,021,339 |
Let's try dividing by 4:
331,021,339 ÷ 4 = 82,755,334.75
If the quotient is a whole number, then 4 and 82,755,334.75 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 | 331,021,339 | |
| -1 | 331,021,339 |
If you did it right, you will end up with this table:
| 1 | 11 | 67 | 101 | 737 | 1,111 | 4,447 | 6,767 | 48,917 | 74,437 | 297,949 | 449,147 | 3,277,439 | 4,940,617 | 30,092,849 | 331,021,339 |
| -1 | -11 | -67 | -101 | -737 | -1,111 | -4,447 | -6,767 | -48,917 | -74,437 | -297,949 | -449,147 | -3,277,439 | -4,940,617 | -30,092,849 | -331,021,339 |
