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 33,305,435, 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 | 33,305,435 | |
| -1 | -33,305,435 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 33,305,435.
Example:
1 x 33,305,435 = 33,305,435
and
-1 x -33,305,435 = 33,305,435
Notice both answers equal 33,305,435
With that explanation out of the way, let's continue. Next, we take the number 33,305,435 and divide it by 2:
33,305,435 ÷ 2 = 16,652,717.5
If the quotient is a whole number, then 2 and 16,652,717.5 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 | 33,305,435 | |
| -1 | -33,305,435 |
Now, we try dividing 33,305,435 by 3:
33,305,435 ÷ 3 = 11,101,811.6667
If the quotient is a whole number, then 3 and 11,101,811.6667 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 | 33,305,435 | |
| -1 | -33,305,435 |
Let's try dividing by 4:
33,305,435 ÷ 4 = 8,326,358.75
If the quotient is a whole number, then 4 and 8,326,358.75 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 | 33,305,435 | |
| -1 | 33,305,435 |
If you did it right, you will end up with this table:
| 1 | 5 | 43 | 97 | 215 | 485 | 1,597 | 4,171 | 7,985 | 20,855 | 68,671 | 154,909 | 343,355 | 774,545 | 6,661,087 | 33,305,435 |
| -1 | -5 | -43 | -97 | -215 | -485 | -1,597 | -4,171 | -7,985 | -20,855 | -68,671 | -154,909 | -343,355 | -774,545 | -6,661,087 | -33,305,435 |
