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 321,413,323, 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 | 321,413,323 | |
| -1 | -321,413,323 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 321,413,323.
Example:
1 x 321,413,323 = 321,413,323
and
-1 x -321,413,323 = 321,413,323
Notice both answers equal 321,413,323
With that explanation out of the way, let's continue. Next, we take the number 321,413,323 and divide it by 2:
321,413,323 ÷ 2 = 160,706,661.5
If the quotient is a whole number, then 2 and 160,706,661.5 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 | 321,413,323 | |
| -1 | -321,413,323 |
Now, we try dividing 321,413,323 by 3:
321,413,323 ÷ 3 = 107,137,774.3333
If the quotient is a whole number, then 3 and 107,137,774.3333 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 | 321,413,323 | |
| -1 | -321,413,323 |
Let's try dividing by 4:
321,413,323 ÷ 4 = 80,353,330.75
If the quotient is a whole number, then 4 and 80,353,330.75 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 | 321,413,323 | |
| -1 | 321,413,323 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 1,459 | 2,861 | 10,213 | 16,049 | 20,027 | 31,471 | 112,343 | 220,297 | 4,174,199 | 29,219,393 | 45,916,189 | 321,413,323 |
| -1 | -7 | -11 | -77 | -1,459 | -2,861 | -10,213 | -16,049 | -20,027 | -31,471 | -112,343 | -220,297 | -4,174,199 | -29,219,393 | -45,916,189 | -321,413,323 |
