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 321,303,005, 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 | 321,303,005 | |
| -1 | -321,303,005 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 321,303,005.
Example:
1 x 321,303,005 = 321,303,005
and
-1 x -321,303,005 = 321,303,005
Notice both answers equal 321,303,005
With that explanation out of the way, let's continue. Next, we take the number 321,303,005 and divide it by 2:
321,303,005 ÷ 2 = 160,651,502.5
If the quotient is a whole number, then 2 and 160,651,502.5 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 | 321,303,005 | |
| -1 | -321,303,005 |
Now, we try dividing 321,303,005 by 3:
321,303,005 ÷ 3 = 107,101,001.6667
If the quotient is a whole number, then 3 and 107,101,001.6667 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 | 321,303,005 | |
| -1 | -321,303,005 |
Let's try dividing by 4:
321,303,005 ÷ 4 = 80,325,751.25
If the quotient is a whole number, then 4 and 80,325,751.25 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 | 321,303,005 | |
| -1 | 321,303,005 |
If you did it right, you will end up with this table:
| 1 | 5 | 37 | 185 | 467 | 2,335 | 3,719 | 17,279 | 18,595 | 86,395 | 137,603 | 688,015 | 1,736,773 | 8,683,865 | 64,260,601 | 321,303,005 |
| -1 | -5 | -37 | -185 | -467 | -2,335 | -3,719 | -17,279 | -18,595 | -86,395 | -137,603 | -688,015 | -1,736,773 | -8,683,865 | -64,260,601 | -321,303,005 |
