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 33,511,505, 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 | 33,511,505 | |
| -1 | -33,511,505 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 33,511,505.
Example:
1 x 33,511,505 = 33,511,505
and
-1 x -33,511,505 = 33,511,505
Notice both answers equal 33,511,505
With that explanation out of the way, let's continue. Next, we take the number 33,511,505 and divide it by 2:
33,511,505 ÷ 2 = 16,755,752.5
If the quotient is a whole number, then 2 and 16,755,752.5 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 | 33,511,505 | |
| -1 | -33,511,505 |
Now, we try dividing 33,511,505 by 3:
33,511,505 ÷ 3 = 11,170,501.6667
If the quotient is a whole number, then 3 and 11,170,501.6667 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 | 33,511,505 | |
| -1 | -33,511,505 |
Let's try dividing by 4:
33,511,505 ÷ 4 = 8,377,876.25
If the quotient is a whole number, then 4 and 8,377,876.25 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 | 33,511,505 | |
| -1 | 33,511,505 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 109 | 545 | 1,853 | 3,617 | 9,265 | 18,085 | 61,489 | 307,445 | 394,253 | 1,971,265 | 6,702,301 | 33,511,505 |
| -1 | -5 | -17 | -85 | -109 | -545 | -1,853 | -3,617 | -9,265 | -18,085 | -61,489 | -307,445 | -394,253 | -1,971,265 | -6,702,301 | -33,511,505 |
