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 331,011,233, 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 | 331,011,233 | |
| -1 | -331,011,233 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 331,011,233.
Example:
1 x 331,011,233 = 331,011,233
and
-1 x -331,011,233 = 331,011,233
Notice both answers equal 331,011,233
With that explanation out of the way, let's continue. Next, we take the number 331,011,233 and divide it by 2:
331,011,233 ÷ 2 = 165,505,616.5
If the quotient is a whole number, then 2 and 165,505,616.5 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 | 331,011,233 | |
| -1 | -331,011,233 |
Now, we try dividing 331,011,233 by 3:
331,011,233 ÷ 3 = 110,337,077.6667
If the quotient is a whole number, then 3 and 110,337,077.6667 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 | 331,011,233 | |
| -1 | -331,011,233 |
Let's try dividing by 4:
331,011,233 ÷ 4 = 82,752,808.25
If the quotient is a whole number, then 4 and 82,752,808.25 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 | 331,011,233 | |
| -1 | 331,011,233 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 119 | 283 | 1,981 | 4,811 | 9,829 | 33,677 | 68,803 | 167,093 | 1,169,651 | 2,781,607 | 19,471,249 | 47,287,319 | 331,011,233 |
| -1 | -7 | -17 | -119 | -283 | -1,981 | -4,811 | -9,829 | -33,677 | -68,803 | -167,093 | -1,169,651 | -2,781,607 | -19,471,249 | -47,287,319 | -331,011,233 |
