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 33,430,109, 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 | 33,430,109 | |
| -1 | -33,430,109 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 33,430,109.
Example:
1 x 33,430,109 = 33,430,109
and
-1 x -33,430,109 = 33,430,109
Notice both answers equal 33,430,109
With that explanation out of the way, let's continue. Next, we take the number 33,430,109 and divide it by 2:
33,430,109 ÷ 2 = 16,715,054.5
If the quotient is a whole number, then 2 and 16,715,054.5 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 | 33,430,109 | |
| -1 | -33,430,109 |
Now, we try dividing 33,430,109 by 3:
33,430,109 ÷ 3 = 11,143,369.6667
If the quotient is a whole number, then 3 and 11,143,369.6667 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 | 33,430,109 | |
| -1 | -33,430,109 |
Let's try dividing by 4:
33,430,109 ÷ 4 = 8,357,527.25
If the quotient is a whole number, then 4 and 8,357,527.25 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 | 33,430,109 | |
| -1 | 33,430,109 |
If you did it right, you will end up with this table:
| 1 | 17 | 23 | 193 | 391 | 443 | 3,281 | 4,439 | 7,531 | 10,189 | 75,463 | 85,499 | 173,213 | 1,453,483 | 1,966,477 | 33,430,109 |
| -1 | -17 | -23 | -193 | -391 | -443 | -3,281 | -4,439 | -7,531 | -10,189 | -75,463 | -85,499 | -173,213 | -1,453,483 | -1,966,477 | -33,430,109 |
