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 33,500,887, 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 | 33,500,887 | |
| -1 | -33,500,887 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 33,500,887.
Example:
1 x 33,500,887 = 33,500,887
and
-1 x -33,500,887 = 33,500,887
Notice both answers equal 33,500,887
With that explanation out of the way, let's continue. Next, we take the number 33,500,887 and divide it by 2:
33,500,887 ÷ 2 = 16,750,443.5
If the quotient is a whole number, then 2 and 16,750,443.5 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 | 33,500,887 | |
| -1 | -33,500,887 |
Now, we try dividing 33,500,887 by 3:
33,500,887 ÷ 3 = 11,166,962.3333
If the quotient is a whole number, then 3 and 11,166,962.3333 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 | 33,500,887 | |
| -1 | -33,500,887 |
Let's try dividing by 4:
33,500,887 ÷ 4 = 8,375,221.75
If the quotient is a whole number, then 4 and 8,375,221.75 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 | 33,500,887 | |
| -1 | 33,500,887 |
If you did it right, you will end up with this table:
| 1 | 7 | 29 | 203 | 227 | 727 | 1,589 | 5,089 | 6,583 | 21,083 | 46,081 | 147,581 | 165,029 | 1,155,203 | 4,785,841 | 33,500,887 |
| -1 | -7 | -29 | -203 | -227 | -727 | -1,589 | -5,089 | -6,583 | -21,083 | -46,081 | -147,581 | -165,029 | -1,155,203 | -4,785,841 | -33,500,887 |
