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 33,857,239, 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 | 33,857,239 | |
| -1 | -33,857,239 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 33,857,239.
Example:
1 x 33,857,239 = 33,857,239
and
-1 x -33,857,239 = 33,857,239
Notice both answers equal 33,857,239
With that explanation out of the way, let's continue. Next, we take the number 33,857,239 and divide it by 2:
33,857,239 ÷ 2 = 16,928,619.5
If the quotient is a whole number, then 2 and 16,928,619.5 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 | 33,857,239 | |
| -1 | -33,857,239 |
Now, we try dividing 33,857,239 by 3:
33,857,239 ÷ 3 = 11,285,746.3333
If the quotient is a whole number, then 3 and 11,285,746.3333 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 | 33,857,239 | |
| -1 | -33,857,239 |
Let's try dividing by 4:
33,857,239 ÷ 4 = 8,464,309.75
If the quotient is a whole number, then 4 and 8,464,309.75 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 | 33,857,239 | |
| -1 | 33,857,239 |
If you did it right, you will end up with this table:
| 1 | 13 | 29 | 31 | 377 | 403 | 899 | 2,897 | 11,687 | 37,661 | 84,013 | 89,807 | 1,092,169 | 1,167,491 | 2,604,403 | 33,857,239 |
| -1 | -13 | -29 | -31 | -377 | -403 | -899 | -2,897 | -11,687 | -37,661 | -84,013 | -89,807 | -1,092,169 | -1,167,491 | -2,604,403 | -33,857,239 |
