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 321,102,013, 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 | 321,102,013 | |
| -1 | -321,102,013 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 321,102,013.
Example:
1 x 321,102,013 = 321,102,013
and
-1 x -321,102,013 = 321,102,013
Notice both answers equal 321,102,013
With that explanation out of the way, let's continue. Next, we take the number 321,102,013 and divide it by 2:
321,102,013 ÷ 2 = 160,551,006.5
If the quotient is a whole number, then 2 and 160,551,006.5 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 | 321,102,013 | |
| -1 | -321,102,013 |
Now, we try dividing 321,102,013 by 3:
321,102,013 ÷ 3 = 107,034,004.3333
If the quotient is a whole number, then 3 and 107,034,004.3333 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 | 321,102,013 | |
| -1 | -321,102,013 |
Let's try dividing by 4:
321,102,013 ÷ 4 = 80,275,503.25
If the quotient is a whole number, then 4 and 80,275,503.25 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 | 321,102,013 | |
| -1 | 321,102,013 |
If you did it right, you will end up with this table:
| 1 | 59 | 163 | 173 | 193 | 9,617 | 10,207 | 11,387 | 28,199 | 31,459 | 33,389 | 1,663,741 | 1,856,081 | 1,969,951 | 5,442,407 | 321,102,013 |
| -1 | -59 | -163 | -173 | -193 | -9,617 | -10,207 | -11,387 | -28,199 | -31,459 | -33,389 | -1,663,741 | -1,856,081 | -1,969,951 | -5,442,407 | -321,102,013 |
