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 322,301,221, 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 | 322,301,221 | |
| -1 | -322,301,221 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 322,301,221.
Example:
1 x 322,301,221 = 322,301,221
and
-1 x -322,301,221 = 322,301,221
Notice both answers equal 322,301,221
With that explanation out of the way, let's continue. Next, we take the number 322,301,221 and divide it by 2:
322,301,221 ÷ 2 = 161,150,610.5
If the quotient is a whole number, then 2 and 161,150,610.5 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 | 322,301,221 | |
| -1 | -322,301,221 |
Now, we try dividing 322,301,221 by 3:
322,301,221 ÷ 3 = 107,433,740.3333
If the quotient is a whole number, then 3 and 107,433,740.3333 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 | 322,301,221 | |
| -1 | -322,301,221 |
Let's try dividing by 4:
322,301,221 ÷ 4 = 80,575,305.25
If the quotient is a whole number, then 4 and 80,575,305.25 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 | 322,301,221 | |
| -1 | 322,301,221 |
If you did it right, you will end up with this table:
| 1 | 11 | 97 | 379 | 797 | 1,067 | 4,169 | 8,767 | 36,763 | 77,309 | 302,063 | 404,393 | 850,399 | 3,322,693 | 29,300,111 | 322,301,221 |
| -1 | -11 | -97 | -379 | -797 | -1,067 | -4,169 | -8,767 | -36,763 | -77,309 | -302,063 | -404,393 | -850,399 | -3,322,693 | -29,300,111 | -322,301,221 |
