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 33,784,033, 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 | 33,784,033 | |
| -1 | -33,784,033 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 33,784,033.
Example:
1 x 33,784,033 = 33,784,033
and
-1 x -33,784,033 = 33,784,033
Notice both answers equal 33,784,033
With that explanation out of the way, let's continue. Next, we take the number 33,784,033 and divide it by 2:
33,784,033 ÷ 2 = 16,892,016.5
If the quotient is a whole number, then 2 and 16,892,016.5 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 | 33,784,033 | |
| -1 | -33,784,033 |
Now, we try dividing 33,784,033 by 3:
33,784,033 ÷ 3 = 11,261,344.3333
If the quotient is a whole number, then 3 and 11,261,344.3333 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 | 33,784,033 | |
| -1 | -33,784,033 |
Let's try dividing by 4:
33,784,033 ÷ 4 = 8,446,008.25
If the quotient is a whole number, then 4 and 8,446,008.25 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 | 33,784,033 | |
| -1 | 33,784,033 |
If you did it right, you will end up with this table:
| 1 | 19 | 23 | 97 | 437 | 797 | 1,843 | 2,231 | 15,143 | 18,331 | 42,389 | 77,309 | 348,289 | 1,468,871 | 1,778,107 | 33,784,033 |
| -1 | -19 | -23 | -97 | -437 | -797 | -1,843 | -2,231 | -15,143 | -18,331 | -42,389 | -77,309 | -348,289 | -1,468,871 | -1,778,107 | -33,784,033 |
