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 33,321,001, 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 | 33,321,001 | |
| -1 | -33,321,001 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 33,321,001.
Example:
1 x 33,321,001 = 33,321,001
and
-1 x -33,321,001 = 33,321,001
Notice both answers equal 33,321,001
With that explanation out of the way, let's continue. Next, we take the number 33,321,001 and divide it by 2:
33,321,001 ÷ 2 = 16,660,500.5
If the quotient is a whole number, then 2 and 16,660,500.5 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 | 33,321,001 | |
| -1 | -33,321,001 |
Now, we try dividing 33,321,001 by 3:
33,321,001 ÷ 3 = 11,107,000.3333
If the quotient is a whole number, then 3 and 11,107,000.3333 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 | 33,321,001 | |
| -1 | -33,321,001 |
Let's try dividing by 4:
33,321,001 ÷ 4 = 8,330,250.25
If the quotient is a whole number, then 4 and 8,330,250.25 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 | 33,321,001 | |
| -1 | 33,321,001 |
If you did it right, you will end up with this table:
| 1 | 7 | 31 | 43 | 217 | 301 | 1,333 | 3,571 | 9,331 | 24,997 | 110,701 | 153,553 | 774,907 | 1,074,871 | 4,760,143 | 33,321,001 |
| -1 | -7 | -31 | -43 | -217 | -301 | -1,333 | -3,571 | -9,331 | -24,997 | -110,701 | -153,553 | -774,907 | -1,074,871 | -4,760,143 | -33,321,001 |
