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 33,555,691, 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 | 33,555,691 | |
| -1 | -33,555,691 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 33,555,691.
Example:
1 x 33,555,691 = 33,555,691
and
-1 x -33,555,691 = 33,555,691
Notice both answers equal 33,555,691
With that explanation out of the way, let's continue. Next, we take the number 33,555,691 and divide it by 2:
33,555,691 ÷ 2 = 16,777,845.5
If the quotient is a whole number, then 2 and 16,777,845.5 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 | 33,555,691 | |
| -1 | -33,555,691 |
Now, we try dividing 33,555,691 by 3:
33,555,691 ÷ 3 = 11,185,230.3333
If the quotient is a whole number, then 3 and 11,185,230.3333 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 | 33,555,691 | |
| -1 | -33,555,691 |
Let's try dividing by 4:
33,555,691 ÷ 4 = 8,388,922.75
If the quotient is a whole number, then 4 and 8,388,922.75 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 | 33,555,691 | |
| -1 | 33,555,691 |
If you did it right, you will end up with this table:
| 1 | 13 | 19 | 73 | 247 | 949 | 1,387 | 1,861 | 18,031 | 24,193 | 35,359 | 135,853 | 459,667 | 1,766,089 | 2,581,207 | 33,555,691 |
| -1 | -13 | -19 | -73 | -247 | -949 | -1,387 | -1,861 | -18,031 | -24,193 | -35,359 | -135,853 | -459,667 | -1,766,089 | -2,581,207 | -33,555,691 |
