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 33,200,531, 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 | 33,200,531 | |
| -1 | -33,200,531 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 33,200,531.
Example:
1 x 33,200,531 = 33,200,531
and
-1 x -33,200,531 = 33,200,531
Notice both answers equal 33,200,531
With that explanation out of the way, let's continue. Next, we take the number 33,200,531 and divide it by 2:
33,200,531 ÷ 2 = 16,600,265.5
If the quotient is a whole number, then 2 and 16,600,265.5 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 | 33,200,531 | |
| -1 | -33,200,531 |
Now, we try dividing 33,200,531 by 3:
33,200,531 ÷ 3 = 11,066,843.6667
If the quotient is a whole number, then 3 and 11,066,843.6667 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 | 33,200,531 | |
| -1 | -33,200,531 |
Let's try dividing by 4:
33,200,531 ÷ 4 = 8,300,132.75
If the quotient is a whole number, then 4 and 8,300,132.75 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 | 33,200,531 | |
| -1 | 33,200,531 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 61 | 91 | 427 | 793 | 5,551 | 5,981 | 41,867 | 77,753 | 364,841 | 544,271 | 2,553,887 | 4,742,933 | 33,200,531 |
| -1 | -7 | -13 | -61 | -91 | -427 | -793 | -5,551 | -5,981 | -41,867 | -77,753 | -364,841 | -544,271 | -2,553,887 | -4,742,933 | -33,200,531 |
