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 33,133,177, 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 | 33,133,177 | |
| -1 | -33,133,177 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 33,133,177.
Example:
1 x 33,133,177 = 33,133,177
and
-1 x -33,133,177 = 33,133,177
Notice both answers equal 33,133,177
With that explanation out of the way, let's continue. Next, we take the number 33,133,177 and divide it by 2:
33,133,177 ÷ 2 = 16,566,588.5
If the quotient is a whole number, then 2 and 16,566,588.5 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 | 33,133,177 | |
| -1 | -33,133,177 |
Now, we try dividing 33,133,177 by 3:
33,133,177 ÷ 3 = 11,044,392.3333
If the quotient is a whole number, then 3 and 11,044,392.3333 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 | 33,133,177 | |
| -1 | -33,133,177 |
Let's try dividing by 4:
33,133,177 ÷ 4 = 8,283,294.25
If the quotient is a whole number, then 4 and 8,283,294.25 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 | 33,133,177 | |
| -1 | 33,133,177 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 43 | 77 | 301 | 473 | 3,311 | 10,007 | 70,049 | 110,077 | 430,301 | 770,539 | 3,012,107 | 4,733,311 | 33,133,177 |
| -1 | -7 | -11 | -43 | -77 | -301 | -473 | -3,311 | -10,007 | -70,049 | -110,077 | -430,301 | -770,539 | -3,012,107 | -4,733,311 | -33,133,177 |
