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 332,190,205, 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 | 332,190,205 | |
| -1 | -332,190,205 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 332,190,205.
Example:
1 x 332,190,205 = 332,190,205
and
-1 x -332,190,205 = 332,190,205
Notice both answers equal 332,190,205
With that explanation out of the way, let's continue. Next, we take the number 332,190,205 and divide it by 2:
332,190,205 ÷ 2 = 166,095,102.5
If the quotient is a whole number, then 2 and 166,095,102.5 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 | 332,190,205 | |
| -1 | -332,190,205 |
Now, we try dividing 332,190,205 by 3:
332,190,205 ÷ 3 = 110,730,068.3333
If the quotient is a whole number, then 3 and 110,730,068.3333 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 | 332,190,205 | |
| -1 | -332,190,205 |
Let's try dividing by 4:
332,190,205 ÷ 4 = 83,047,551.25
If the quotient is a whole number, then 4 and 83,047,551.25 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 | 332,190,205 | |
| -1 | 332,190,205 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 95 | 181 | 905 | 3,439 | 17,195 | 19,319 | 96,595 | 367,061 | 1,835,305 | 3,496,739 | 17,483,695 | 66,438,041 | 332,190,205 |
| -1 | -5 | -19 | -95 | -181 | -905 | -3,439 | -17,195 | -19,319 | -96,595 | -367,061 | -1,835,305 | -3,496,739 | -17,483,695 | -66,438,041 | -332,190,205 |
