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 30,033,235, 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 | 30,033,235 | |
| -1 | -30,033,235 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 30,033,235.
Example:
1 x 30,033,235 = 30,033,235
and
-1 x -30,033,235 = 30,033,235
Notice both answers equal 30,033,235
With that explanation out of the way, let's continue. Next, we take the number 30,033,235 and divide it by 2:
30,033,235 ÷ 2 = 15,016,617.5
If the quotient is a whole number, then 2 and 15,016,617.5 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 | 30,033,235 | |
| -1 | -30,033,235 |
Now, we try dividing 30,033,235 by 3:
30,033,235 ÷ 3 = 10,011,078.3333
If the quotient is a whole number, then 3 and 10,011,078.3333 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 | 30,033,235 | |
| -1 | -30,033,235 |
Let's try dividing by 4:
30,033,235 ÷ 4 = 7,508,308.75
If the quotient is a whole number, then 4 and 7,508,308.75 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 | 30,033,235 | |
| -1 | 30,033,235 |
If you did it right, you will end up with this table:
| 1 | 5 | 47 | 227 | 235 | 563 | 1,135 | 2,815 | 10,669 | 26,461 | 53,345 | 127,801 | 132,305 | 639,005 | 6,006,647 | 30,033,235 |
| -1 | -5 | -47 | -227 | -235 | -563 | -1,135 | -2,815 | -10,669 | -26,461 | -53,345 | -127,801 | -132,305 | -639,005 | -6,006,647 | -30,033,235 |
