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 33,511,415, 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 | 33,511,415 | |
| -1 | -33,511,415 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 33,511,415.
Example:
1 x 33,511,415 = 33,511,415
and
-1 x -33,511,415 = 33,511,415
Notice both answers equal 33,511,415
With that explanation out of the way, let's continue. Next, we take the number 33,511,415 and divide it by 2:
33,511,415 ÷ 2 = 16,755,707.5
If the quotient is a whole number, then 2 and 16,755,707.5 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 | 33,511,415 | |
| -1 | -33,511,415 |
Now, we try dividing 33,511,415 by 3:
33,511,415 ÷ 3 = 11,170,471.6667
If the quotient is a whole number, then 3 and 11,170,471.6667 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 | 33,511,415 | |
| -1 | -33,511,415 |
Let's try dividing by 4:
33,511,415 ÷ 4 = 8,377,853.75
If the quotient is a whole number, then 4 and 8,377,853.75 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 | 33,511,415 | |
| -1 | 33,511,415 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 409 | 2,045 | 2,341 | 2,863 | 11,705 | 14,315 | 16,387 | 81,935 | 957,469 | 4,787,345 | 6,702,283 | 33,511,415 |
| -1 | -5 | -7 | -35 | -409 | -2,045 | -2,341 | -2,863 | -11,705 | -14,315 | -16,387 | -81,935 | -957,469 | -4,787,345 | -6,702,283 | -33,511,415 |
