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 332,222,215, 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 | 332,222,215 | |
| -1 | -332,222,215 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 332,222,215.
Example:
1 x 332,222,215 = 332,222,215
and
-1 x -332,222,215 = 332,222,215
Notice both answers equal 332,222,215
With that explanation out of the way, let's continue. Next, we take the number 332,222,215 and divide it by 2:
332,222,215 ÷ 2 = 166,111,107.5
If the quotient is a whole number, then 2 and 166,111,107.5 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 | 332,222,215 | |
| -1 | -332,222,215 |
Now, we try dividing 332,222,215 by 3:
332,222,215 ÷ 3 = 110,740,738.3333
If the quotient is a whole number, then 3 and 110,740,738.3333 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 | 332,222,215 | |
| -1 | -332,222,215 |
Let's try dividing by 4:
332,222,215 ÷ 4 = 83,055,553.75
If the quotient is a whole number, then 4 and 83,055,553.75 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 | 332,222,215 | |
| -1 | 332,222,215 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 59 | 65 | 295 | 767 | 3,835 | 86,629 | 433,145 | 1,126,177 | 5,111,111 | 5,630,885 | 25,555,555 | 66,444,443 | 332,222,215 |
| -1 | -5 | -13 | -59 | -65 | -295 | -767 | -3,835 | -86,629 | -433,145 | -1,126,177 | -5,111,111 | -5,630,885 | -25,555,555 | -66,444,443 | -332,222,215 |
