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 33,507,035, 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 | 33,507,035 | |
| -1 | -33,507,035 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 33,507,035.
Example:
1 x 33,507,035 = 33,507,035
and
-1 x -33,507,035 = 33,507,035
Notice both answers equal 33,507,035
With that explanation out of the way, let's continue. Next, we take the number 33,507,035 and divide it by 2:
33,507,035 ÷ 2 = 16,753,517.5
If the quotient is a whole number, then 2 and 16,753,517.5 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 | 33,507,035 | |
| -1 | -33,507,035 |
Now, we try dividing 33,507,035 by 3:
33,507,035 ÷ 3 = 11,169,011.6667
If the quotient is a whole number, then 3 and 11,169,011.6667 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 | 33,507,035 | |
| -1 | -33,507,035 |
Let's try dividing by 4:
33,507,035 ÷ 4 = 8,376,758.75
If the quotient is a whole number, then 4 and 8,376,758.75 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 | 33,507,035 | |
| -1 | 33,507,035 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 67 | 145 | 335 | 1,943 | 3,449 | 9,715 | 17,245 | 100,021 | 231,083 | 500,105 | 1,155,415 | 6,701,407 | 33,507,035 |
| -1 | -5 | -29 | -67 | -145 | -335 | -1,943 | -3,449 | -9,715 | -17,245 | -100,021 | -231,083 | -500,105 | -1,155,415 | -6,701,407 | -33,507,035 |
