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 33,027,841, 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 | 33,027,841 | |
| -1 | -33,027,841 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 33,027,841.
Example:
1 x 33,027,841 = 33,027,841
and
-1 x -33,027,841 = 33,027,841
Notice both answers equal 33,027,841
With that explanation out of the way, let's continue. Next, we take the number 33,027,841 and divide it by 2:
33,027,841 ÷ 2 = 16,513,920.5
If the quotient is a whole number, then 2 and 16,513,920.5 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 | 33,027,841 | |
| -1 | -33,027,841 |
Now, we try dividing 33,027,841 by 3:
33,027,841 ÷ 3 = 11,009,280.3333
If the quotient is a whole number, then 3 and 11,009,280.3333 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 | 33,027,841 | |
| -1 | -33,027,841 |
Let's try dividing by 4:
33,027,841 ÷ 4 = 8,256,960.25
If the quotient is a whole number, then 4 and 8,256,960.25 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 | 33,027,841 | |
| -1 | 33,027,841 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 257 | 1,669 | 1,799 | 2,827 | 11,683 | 18,359 | 19,789 | 128,513 | 428,933 | 3,002,531 | 4,718,263 | 33,027,841 |
| -1 | -7 | -11 | -77 | -257 | -1,669 | -1,799 | -2,827 | -11,683 | -18,359 | -19,789 | -128,513 | -428,933 | -3,002,531 | -4,718,263 | -33,027,841 |
