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 321,111,049, 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 | 321,111,049 | |
| -1 | -321,111,049 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 321,111,049.
Example:
1 x 321,111,049 = 321,111,049
and
-1 x -321,111,049 = 321,111,049
Notice both answers equal 321,111,049
With that explanation out of the way, let's continue. Next, we take the number 321,111,049 and divide it by 2:
321,111,049 ÷ 2 = 160,555,524.5
If the quotient is a whole number, then 2 and 160,555,524.5 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 | 321,111,049 | |
| -1 | -321,111,049 |
Now, we try dividing 321,111,049 by 3:
321,111,049 ÷ 3 = 107,037,016.3333
If the quotient is a whole number, then 3 and 107,037,016.3333 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 | 321,111,049 | |
| -1 | -321,111,049 |
Let's try dividing by 4:
321,111,049 ÷ 4 = 80,277,762.25
If the quotient is a whole number, then 4 and 80,277,762.25 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 | 321,111,049 | |
| -1 | 321,111,049 |
If you did it right, you will end up with this table:
| 1 | 7 | 37 | 103 | 259 | 721 | 3,811 | 12,037 | 26,677 | 84,259 | 445,369 | 1,239,811 | 3,117,583 | 8,678,677 | 45,873,007 | 321,111,049 |
| -1 | -7 | -37 | -103 | -259 | -721 | -3,811 | -12,037 | -26,677 | -84,259 | -445,369 | -1,239,811 | -3,117,583 | -8,678,677 | -45,873,007 | -321,111,049 |
