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 33,200,765, 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 | 33,200,765 | |
| -1 | -33,200,765 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 33,200,765.
Example:
1 x 33,200,765 = 33,200,765
and
-1 x -33,200,765 = 33,200,765
Notice both answers equal 33,200,765
With that explanation out of the way, let's continue. Next, we take the number 33,200,765 and divide it by 2:
33,200,765 ÷ 2 = 16,600,382.5
If the quotient is a whole number, then 2 and 16,600,382.5 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 | 33,200,765 | |
| -1 | -33,200,765 |
Now, we try dividing 33,200,765 by 3:
33,200,765 ÷ 3 = 11,066,921.6667
If the quotient is a whole number, then 3 and 11,066,921.6667 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 | 33,200,765 | |
| -1 | -33,200,765 |
Let's try dividing by 4:
33,200,765 ÷ 4 = 8,300,191.25
If the quotient is a whole number, then 4 and 8,300,191.25 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 | 33,200,765 | |
| -1 | 33,200,765 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 73 | 365 | 949 | 4,745 | 6,997 | 34,985 | 90,961 | 454,805 | 510,781 | 2,553,905 | 6,640,153 | 33,200,765 |
| -1 | -5 | -13 | -65 | -73 | -365 | -949 | -4,745 | -6,997 | -34,985 | -90,961 | -454,805 | -510,781 | -2,553,905 | -6,640,153 | -33,200,765 |
