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 30,324,245, 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 | 30,324,245 | |
| -1 | -30,324,245 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 30,324,245.
Example:
1 x 30,324,245 = 30,324,245
and
-1 x -30,324,245 = 30,324,245
Notice both answers equal 30,324,245
With that explanation out of the way, let's continue. Next, we take the number 30,324,245 and divide it by 2:
30,324,245 ÷ 2 = 15,162,122.5
If the quotient is a whole number, then 2 and 15,162,122.5 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 | 30,324,245 | |
| -1 | -30,324,245 |
Now, we try dividing 30,324,245 by 3:
30,324,245 ÷ 3 = 10,108,081.6667
If the quotient is a whole number, then 3 and 10,108,081.6667 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 | 30,324,245 | |
| -1 | -30,324,245 |
Let's try dividing by 4:
30,324,245 ÷ 4 = 7,581,061.25
If the quotient is a whole number, then 4 and 7,581,061.25 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 | 30,324,245 | |
| -1 | 30,324,245 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 43 | 215 | 301 | 1,505 | 20,149 | 100,745 | 141,043 | 705,215 | 866,407 | 4,332,035 | 6,064,849 | 30,324,245 |
| -1 | -5 | -7 | -35 | -43 | -215 | -301 | -1,505 | -20,149 | -100,745 | -141,043 | -705,215 | -866,407 | -4,332,035 | -6,064,849 | -30,324,245 |
