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 321,233,203, 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 | 321,233,203 | |
| -1 | -321,233,203 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 321,233,203.
Example:
1 x 321,233,203 = 321,233,203
and
-1 x -321,233,203 = 321,233,203
Notice both answers equal 321,233,203
With that explanation out of the way, let's continue. Next, we take the number 321,233,203 and divide it by 2:
321,233,203 ÷ 2 = 160,616,601.5
If the quotient is a whole number, then 2 and 160,616,601.5 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 | 321,233,203 | |
| -1 | -321,233,203 |
Now, we try dividing 321,233,203 by 3:
321,233,203 ÷ 3 = 107,077,734.3333
If the quotient is a whole number, then 3 and 107,077,734.3333 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 | 321,233,203 | |
| -1 | -321,233,203 |
Let's try dividing by 4:
321,233,203 ÷ 4 = 80,308,300.75
If the quotient is a whole number, then 4 and 80,308,300.75 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 | 321,233,203 | |
| -1 | 321,233,203 |
If you did it right, you will end up with this table:
| 1 | 23 | 29 | 47 | 667 | 1,081 | 1,363 | 10,247 | 31,349 | 235,681 | 297,163 | 481,609 | 6,834,749 | 11,077,007 | 13,966,661 | 321,233,203 |
| -1 | -23 | -29 | -47 | -667 | -1,081 | -1,363 | -10,247 | -31,349 | -235,681 | -297,163 | -481,609 | -6,834,749 | -11,077,007 | -13,966,661 | -321,233,203 |
