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 331,201,241, 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 | 331,201,241 | |
| -1 | -331,201,241 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 331,201,241.
Example:
1 x 331,201,241 = 331,201,241
and
-1 x -331,201,241 = 331,201,241
Notice both answers equal 331,201,241
With that explanation out of the way, let's continue. Next, we take the number 331,201,241 and divide it by 2:
331,201,241 ÷ 2 = 165,600,620.5
If the quotient is a whole number, then 2 and 165,600,620.5 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 | 331,201,241 | |
| -1 | -331,201,241 |
Now, we try dividing 331,201,241 by 3:
331,201,241 ÷ 3 = 110,400,413.6667
If the quotient is a whole number, then 3 and 110,400,413.6667 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 | 331,201,241 | |
| -1 | -331,201,241 |
Let's try dividing by 4:
331,201,241 ÷ 4 = 82,800,310.25
If the quotient is a whole number, then 4 and 82,800,310.25 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 | 331,201,241 | |
| -1 | 331,201,241 |
If you did it right, you will end up with this table:
| 1 | 7 | 31 | 49 | 217 | 337 | 647 | 1,519 | 2,359 | 4,529 | 10,447 | 16,513 | 20,057 | 31,703 | 73,129 | 140,399 | 218,039 | 511,903 | 982,793 | 1,526,273 | 6,759,209 | 10,683,911 | 47,314,463 | 331,201,241 |
| -1 | -7 | -31 | -49 | -217 | -337 | -647 | -1,519 | -2,359 | -4,529 | -10,447 | -16,513 | -20,057 | -31,703 | -73,129 | -140,399 | -218,039 | -511,903 | -982,793 | -1,526,273 | -6,759,209 | -10,683,911 | -47,314,463 | -331,201,241 |
