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 33,178,765, 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 | 33,178,765 | |
| -1 | -33,178,765 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 33,178,765.
Example:
1 x 33,178,765 = 33,178,765
and
-1 x -33,178,765 = 33,178,765
Notice both answers equal 33,178,765
With that explanation out of the way, let's continue. Next, we take the number 33,178,765 and divide it by 2:
33,178,765 ÷ 2 = 16,589,382.5
If the quotient is a whole number, then 2 and 16,589,382.5 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 | 33,178,765 | |
| -1 | -33,178,765 |
Now, we try dividing 33,178,765 by 3:
33,178,765 ÷ 3 = 11,059,588.3333
If the quotient is a whole number, then 3 and 11,059,588.3333 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 | 33,178,765 | |
| -1 | -33,178,765 |
Let's try dividing by 4:
33,178,765 ÷ 4 = 8,294,691.25
If the quotient is a whole number, then 4 and 8,294,691.25 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 | 33,178,765 | |
| -1 | 33,178,765 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 115 | 263 | 1,097 | 1,315 | 5,485 | 6,049 | 25,231 | 30,245 | 126,155 | 288,511 | 1,442,555 | 6,635,753 | 33,178,765 |
| -1 | -5 | -23 | -115 | -263 | -1,097 | -1,315 | -5,485 | -6,049 | -25,231 | -30,245 | -126,155 | -288,511 | -1,442,555 | -6,635,753 | -33,178,765 |
