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 30,933,995, 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 | 30,933,995 | |
| -1 | -30,933,995 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 30,933,995.
Example:
1 x 30,933,995 = 30,933,995
and
-1 x -30,933,995 = 30,933,995
Notice both answers equal 30,933,995
With that explanation out of the way, let's continue. Next, we take the number 30,933,995 and divide it by 2:
30,933,995 ÷ 2 = 15,466,997.5
If the quotient is a whole number, then 2 and 15,466,997.5 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 | 30,933,995 | |
| -1 | -30,933,995 |
Now, we try dividing 30,933,995 by 3:
30,933,995 ÷ 3 = 10,311,331.6667
If the quotient is a whole number, then 3 and 10,311,331.6667 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 | 30,933,995 | |
| -1 | -30,933,995 |
Let's try dividing by 4:
30,933,995 ÷ 4 = 7,733,498.75
If the quotient is a whole number, then 4 and 7,733,498.75 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 | 30,933,995 | |
| -1 | 30,933,995 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 59 | 95 | 295 | 1,121 | 5,519 | 5,605 | 27,595 | 104,861 | 325,621 | 524,305 | 1,628,105 | 6,186,799 | 30,933,995 |
| -1 | -5 | -19 | -59 | -95 | -295 | -1,121 | -5,519 | -5,605 | -27,595 | -104,861 | -325,621 | -524,305 | -1,628,105 | -6,186,799 | -30,933,995 |
