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 33,678,887, 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 | 33,678,887 | |
| -1 | -33,678,887 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 33,678,887.
Example:
1 x 33,678,887 = 33,678,887
and
-1 x -33,678,887 = 33,678,887
Notice both answers equal 33,678,887
With that explanation out of the way, let's continue. Next, we take the number 33,678,887 and divide it by 2:
33,678,887 ÷ 2 = 16,839,443.5
If the quotient is a whole number, then 2 and 16,839,443.5 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 | 33,678,887 | |
| -1 | -33,678,887 |
Now, we try dividing 33,678,887 by 3:
33,678,887 ÷ 3 = 11,226,295.6667
If the quotient is a whole number, then 3 and 11,226,295.6667 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 | 33,678,887 | |
| -1 | -33,678,887 |
Let's try dividing by 4:
33,678,887 ÷ 4 = 8,419,721.75
If the quotient is a whole number, then 4 and 8,419,721.75 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 | 33,678,887 | |
| -1 | 33,678,887 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 19 | 187 | 209 | 323 | 3,553 | 9,479 | 104,269 | 161,143 | 180,101 | 1,772,573 | 1,981,111 | 3,061,717 | 33,678,887 |
| -1 | -11 | -17 | -19 | -187 | -209 | -323 | -3,553 | -9,479 | -104,269 | -161,143 | -180,101 | -1,772,573 | -1,981,111 | -3,061,717 | -33,678,887 |
