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 33,217,205, 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 | 33,217,205 | |
| -1 | -33,217,205 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 33,217,205.
Example:
1 x 33,217,205 = 33,217,205
and
-1 x -33,217,205 = 33,217,205
Notice both answers equal 33,217,205
With that explanation out of the way, let's continue. Next, we take the number 33,217,205 and divide it by 2:
33,217,205 ÷ 2 = 16,608,602.5
If the quotient is a whole number, then 2 and 16,608,602.5 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 | 33,217,205 | |
| -1 | -33,217,205 |
Now, we try dividing 33,217,205 by 3:
33,217,205 ÷ 3 = 11,072,401.6667
If the quotient is a whole number, then 3 and 11,072,401.6667 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 | 33,217,205 | |
| -1 | -33,217,205 |
Let's try dividing by 4:
33,217,205 ÷ 4 = 8,304,301.25
If the quotient is a whole number, then 4 and 8,304,301.25 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 | 33,217,205 | |
| -1 | 33,217,205 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 109 | 545 | 763 | 3,815 | 8,707 | 43,535 | 60,949 | 304,745 | 949,063 | 4,745,315 | 6,643,441 | 33,217,205 |
| -1 | -5 | -7 | -35 | -109 | -545 | -763 | -3,815 | -8,707 | -43,535 | -60,949 | -304,745 | -949,063 | -4,745,315 | -6,643,441 | -33,217,205 |
