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 331,410,245, 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 | 331,410,245 | |
| -1 | -331,410,245 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 331,410,245.
Example:
1 x 331,410,245 = 331,410,245
and
-1 x -331,410,245 = 331,410,245
Notice both answers equal 331,410,245
With that explanation out of the way, let's continue. Next, we take the number 331,410,245 and divide it by 2:
331,410,245 ÷ 2 = 165,705,122.5
If the quotient is a whole number, then 2 and 165,705,122.5 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 | 331,410,245 | |
| -1 | -331,410,245 |
Now, we try dividing 331,410,245 by 3:
331,410,245 ÷ 3 = 110,470,081.6667
If the quotient is a whole number, then 3 and 110,470,081.6667 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 | 331,410,245 | |
| -1 | -331,410,245 |
Let's try dividing by 4:
331,410,245 ÷ 4 = 82,852,561.25
If the quotient is a whole number, then 4 and 82,852,561.25 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 | 331,410,245 | |
| -1 | 331,410,245 |
If you did it right, you will end up with this table:
| 1 | 5 | 43 | 215 | 263 | 1,315 | 5,861 | 11,309 | 29,305 | 56,545 | 252,023 | 1,260,115 | 1,541,443 | 7,707,215 | 66,282,049 | 331,410,245 |
| -1 | -5 | -43 | -215 | -263 | -1,315 | -5,861 | -11,309 | -29,305 | -56,545 | -252,023 | -1,260,115 | -1,541,443 | -7,707,215 | -66,282,049 | -331,410,245 |
