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 30,232,205, 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 | 30,232,205 | |
| -1 | -30,232,205 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 30,232,205.
Example:
1 x 30,232,205 = 30,232,205
and
-1 x -30,232,205 = 30,232,205
Notice both answers equal 30,232,205
With that explanation out of the way, let's continue. Next, we take the number 30,232,205 and divide it by 2:
30,232,205 ÷ 2 = 15,116,102.5
If the quotient is a whole number, then 2 and 15,116,102.5 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 | 30,232,205 | |
| -1 | -30,232,205 |
Now, we try dividing 30,232,205 by 3:
30,232,205 ÷ 3 = 10,077,401.6667
If the quotient is a whole number, then 3 and 10,077,401.6667 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 | 30,232,205 | |
| -1 | -30,232,205 |
Let's try dividing by 4:
30,232,205 ÷ 4 = 7,558,051.25
If the quotient is a whole number, then 4 and 7,558,051.25 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 | 30,232,205 | |
| -1 | 30,232,205 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 179 | 895 | 1,987 | 3,043 | 9,935 | 15,215 | 33,779 | 168,895 | 355,673 | 1,778,365 | 6,046,441 | 30,232,205 |
| -1 | -5 | -17 | -85 | -179 | -895 | -1,987 | -3,043 | -9,935 | -15,215 | -33,779 | -168,895 | -355,673 | -1,778,365 | -6,046,441 | -30,232,205 |
