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 30,232,439, 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 | 30,232,439 | |
| -1 | -30,232,439 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 30,232,439.
Example:
1 x 30,232,439 = 30,232,439
and
-1 x -30,232,439 = 30,232,439
Notice both answers equal 30,232,439
With that explanation out of the way, let's continue. Next, we take the number 30,232,439 and divide it by 2:
30,232,439 ÷ 2 = 15,116,219.5
If the quotient is a whole number, then 2 and 15,116,219.5 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 | 30,232,439 | |
| -1 | -30,232,439 |
Now, we try dividing 30,232,439 by 3:
30,232,439 ÷ 3 = 10,077,479.6667
If the quotient is a whole number, then 3 and 10,077,479.6667 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 | 30,232,439 | |
| -1 | -30,232,439 |
Let's try dividing by 4:
30,232,439 ÷ 4 = 7,558,109.75
If the quotient is a whole number, then 4 and 7,558,109.75 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 | 30,232,439 | |
| -1 | 30,232,439 |
If you did it right, you will end up with this table:
| 1 | 19 | 71 | 73 | 307 | 1,349 | 1,387 | 5,183 | 5,833 | 21,797 | 22,411 | 98,477 | 414,143 | 425,809 | 1,591,181 | 30,232,439 |
| -1 | -19 | -71 | -73 | -307 | -1,349 | -1,387 | -5,183 | -5,833 | -21,797 | -22,411 | -98,477 | -414,143 | -425,809 | -1,591,181 | -30,232,439 |
