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 321,111,229, 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 | 321,111,229 | |
| -1 | -321,111,229 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 321,111,229.
Example:
1 x 321,111,229 = 321,111,229
and
-1 x -321,111,229 = 321,111,229
Notice both answers equal 321,111,229
With that explanation out of the way, let's continue. Next, we take the number 321,111,229 and divide it by 2:
321,111,229 ÷ 2 = 160,555,614.5
If the quotient is a whole number, then 2 and 160,555,614.5 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 | 321,111,229 | |
| -1 | -321,111,229 |
Now, we try dividing 321,111,229 by 3:
321,111,229 ÷ 3 = 107,037,076.3333
If the quotient is a whole number, then 3 and 107,037,076.3333 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 | 321,111,229 | |
| -1 | -321,111,229 |
Let's try dividing by 4:
321,111,229 ÷ 4 = 80,277,807.25
If the quotient is a whole number, then 4 and 80,277,807.25 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 | 321,111,229 | |
| -1 | 321,111,229 |
If you did it right, you will end up with this table:
| 1 | 19 | 29 | 43 | 551 | 817 | 1,247 | 13,553 | 23,693 | 257,507 | 393,037 | 582,779 | 7,467,703 | 11,072,801 | 16,900,591 | 321,111,229 |
| -1 | -19 | -29 | -43 | -551 | -817 | -1,247 | -13,553 | -23,693 | -257,507 | -393,037 | -582,779 | -7,467,703 | -11,072,801 | -16,900,591 | -321,111,229 |
