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 33,181,165, 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 | 33,181,165 | |
| -1 | -33,181,165 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 33,181,165.
Example:
1 x 33,181,165 = 33,181,165
and
-1 x -33,181,165 = 33,181,165
Notice both answers equal 33,181,165
With that explanation out of the way, let's continue. Next, we take the number 33,181,165 and divide it by 2:
33,181,165 ÷ 2 = 16,590,582.5
If the quotient is a whole number, then 2 and 16,590,582.5 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 | 33,181,165 | |
| -1 | -33,181,165 |
Now, we try dividing 33,181,165 by 3:
33,181,165 ÷ 3 = 11,060,388.3333
If the quotient is a whole number, then 3 and 11,060,388.3333 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 | 33,181,165 | |
| -1 | -33,181,165 |
Let's try dividing by 4:
33,181,165 ÷ 4 = 8,295,291.25
If the quotient is a whole number, then 4 and 8,295,291.25 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 | 33,181,165 | |
| -1 | 33,181,165 |
If you did it right, you will end up with this table:
| 1 | 5 | 43 | 157 | 215 | 785 | 983 | 4,915 | 6,751 | 33,755 | 42,269 | 154,331 | 211,345 | 771,655 | 6,636,233 | 33,181,165 |
| -1 | -5 | -43 | -157 | -215 | -785 | -983 | -4,915 | -6,751 | -33,755 | -42,269 | -154,331 | -211,345 | -771,655 | -6,636,233 | -33,181,165 |
