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 331,204,727, 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 | 331,204,727 | |
| -1 | -331,204,727 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 331,204,727.
Example:
1 x 331,204,727 = 331,204,727
and
-1 x -331,204,727 = 331,204,727
Notice both answers equal 331,204,727
With that explanation out of the way, let's continue. Next, we take the number 331,204,727 and divide it by 2:
331,204,727 ÷ 2 = 165,602,363.5
If the quotient is a whole number, then 2 and 165,602,363.5 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 | 331,204,727 | |
| -1 | -331,204,727 |
Now, we try dividing 331,204,727 by 3:
331,204,727 ÷ 3 = 110,401,575.6667
If the quotient is a whole number, then 3 and 110,401,575.6667 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 | 331,204,727 | |
| -1 | -331,204,727 |
Let's try dividing by 4:
331,204,727 ÷ 4 = 82,801,181.75
If the quotient is a whole number, then 4 and 82,801,181.75 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 | 331,204,727 | |
| -1 | 331,204,727 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 119 | 947 | 2,939 | 6,629 | 16,099 | 20,573 | 49,963 | 112,693 | 349,741 | 2,783,233 | 19,482,631 | 47,314,961 | 331,204,727 |
| -1 | -7 | -17 | -119 | -947 | -2,939 | -6,629 | -16,099 | -20,573 | -49,963 | -112,693 | -349,741 | -2,783,233 | -19,482,631 | -47,314,961 | -331,204,727 |
