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 241,322,321, 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 | 241,322,321 | |
| -1 | -241,322,321 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 241,322,321.
Example:
1 x 241,322,321 = 241,322,321
and
-1 x -241,322,321 = 241,322,321
Notice both answers equal 241,322,321
With that explanation out of the way, let's continue. Next, we take the number 241,322,321 and divide it by 2:
241,322,321 ÷ 2 = 120,661,160.5
If the quotient is a whole number, then 2 and 120,661,160.5 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 | 241,322,321 | |
| -1 | -241,322,321 |
Now, we try dividing 241,322,321 by 3:
241,322,321 ÷ 3 = 80,440,773.6667
If the quotient is a whole number, then 3 and 80,440,773.6667 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 | 241,322,321 | |
| -1 | -241,322,321 |
Let's try dividing by 4:
241,322,321 ÷ 4 = 60,330,580.25
If the quotient is a whole number, then 4 and 60,330,580.25 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 | 241,322,321 | |
| -1 | 241,322,321 |
If you did it right, you will end up with this table:
| 1 | 31 | 43 | 269 | 673 | 1,333 | 8,339 | 11,567 | 20,863 | 28,939 | 181,037 | 358,577 | 897,109 | 5,612,147 | 7,784,591 | 241,322,321 |
| -1 | -31 | -43 | -269 | -673 | -1,333 | -8,339 | -11,567 | -20,863 | -28,939 | -181,037 | -358,577 | -897,109 | -5,612,147 | -7,784,591 | -241,322,321 |
