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 33,800,515, 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 | 33,800,515 | |
| -1 | -33,800,515 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 33,800,515.
Example:
1 x 33,800,515 = 33,800,515
and
-1 x -33,800,515 = 33,800,515
Notice both answers equal 33,800,515
With that explanation out of the way, let's continue. Next, we take the number 33,800,515 and divide it by 2:
33,800,515 ÷ 2 = 16,900,257.5
If the quotient is a whole number, then 2 and 16,900,257.5 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 | 33,800,515 | |
| -1 | -33,800,515 |
Now, we try dividing 33,800,515 by 3:
33,800,515 ÷ 3 = 11,266,838.3333
If the quotient is a whole number, then 3 and 11,266,838.3333 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 | 33,800,515 | |
| -1 | -33,800,515 |
Let's try dividing by 4:
33,800,515 ÷ 4 = 8,450,128.75
If the quotient is a whole number, then 4 and 8,450,128.75 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 | 33,800,515 | |
| -1 | 33,800,515 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 29 | 35 | 145 | 203 | 1,015 | 33,301 | 166,505 | 233,107 | 965,729 | 1,165,535 | 4,828,645 | 6,760,103 | 33,800,515 |
| -1 | -5 | -7 | -29 | -35 | -145 | -203 | -1,015 | -33,301 | -166,505 | -233,107 | -965,729 | -1,165,535 | -4,828,645 | -6,760,103 | -33,800,515 |
