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 30,082,499, 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 | 30,082,499 | |
| -1 | -30,082,499 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 30,082,499.
Example:
1 x 30,082,499 = 30,082,499
and
-1 x -30,082,499 = 30,082,499
Notice both answers equal 30,082,499
With that explanation out of the way, let's continue. Next, we take the number 30,082,499 and divide it by 2:
30,082,499 ÷ 2 = 15,041,249.5
If the quotient is a whole number, then 2 and 15,041,249.5 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 | 30,082,499 | |
| -1 | -30,082,499 |
Now, we try dividing 30,082,499 by 3:
30,082,499 ÷ 3 = 10,027,499.6667
If the quotient is a whole number, then 3 and 10,027,499.6667 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 | 30,082,499 | |
| -1 | -30,082,499 |
Let's try dividing by 4:
30,082,499 ÷ 4 = 7,520,624.75
If the quotient is a whole number, then 4 and 7,520,624.75 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 | 30,082,499 | |
| -1 | 30,082,499 |
If you did it right, you will end up with this table:
| 1 | 43 | 463 | 1,511 | 19,909 | 64,973 | 699,593 | 30,082,499 |
| -1 | -43 | -463 | -1,511 | -19,909 | -64,973 | -699,593 | -30,082,499 |
