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 33,011,315, 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 | 33,011,315 | |
| -1 | -33,011,315 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 33,011,315.
Example:
1 x 33,011,315 = 33,011,315
and
-1 x -33,011,315 = 33,011,315
Notice both answers equal 33,011,315
With that explanation out of the way, let's continue. Next, we take the number 33,011,315 and divide it by 2:
33,011,315 ÷ 2 = 16,505,657.5
If the quotient is a whole number, then 2 and 16,505,657.5 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 | 33,011,315 | |
| -1 | -33,011,315 |
Now, we try dividing 33,011,315 by 3:
33,011,315 ÷ 3 = 11,003,771.6667
If the quotient is a whole number, then 3 and 11,003,771.6667 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 | 33,011,315 | |
| -1 | -33,011,315 |
Let's try dividing by 4:
33,011,315 ÷ 4 = 8,252,828.75
If the quotient is a whole number, then 4 and 8,252,828.75 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 | 33,011,315 | |
| -1 | 33,011,315 |
If you did it right, you will end up with this table:
| 1 | 5 | 43 | 53 | 215 | 265 | 2,279 | 2,897 | 11,395 | 14,485 | 124,571 | 153,541 | 622,855 | 767,705 | 6,602,263 | 33,011,315 |
| -1 | -5 | -43 | -53 | -215 | -265 | -2,279 | -2,897 | -11,395 | -14,485 | -124,571 | -153,541 | -622,855 | -767,705 | -6,602,263 | -33,011,315 |
