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 33,031,505, 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 | 33,031,505 | |
| -1 | -33,031,505 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 33,031,505.
Example:
1 x 33,031,505 = 33,031,505
and
-1 x -33,031,505 = 33,031,505
Notice both answers equal 33,031,505
With that explanation out of the way, let's continue. Next, we take the number 33,031,505 and divide it by 2:
33,031,505 ÷ 2 = 16,515,752.5
If the quotient is a whole number, then 2 and 16,515,752.5 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 | 33,031,505 | |
| -1 | -33,031,505 |
Now, we try dividing 33,031,505 by 3:
33,031,505 ÷ 3 = 11,010,501.6667
If the quotient is a whole number, then 3 and 11,010,501.6667 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 | 33,031,505 | |
| -1 | -33,031,505 |
Let's try dividing by 4:
33,031,505 ÷ 4 = 8,257,876.25
If the quotient is a whole number, then 4 and 8,257,876.25 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 | 33,031,505 | |
| -1 | 33,031,505 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 613 | 829 | 3,065 | 4,145 | 7,969 | 10,777 | 39,845 | 53,885 | 508,177 | 2,540,885 | 6,606,301 | 33,031,505 |
| -1 | -5 | -13 | -65 | -613 | -829 | -3,065 | -4,145 | -7,969 | -10,777 | -39,845 | -53,885 | -508,177 | -2,540,885 | -6,606,301 | -33,031,505 |
