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 332,783,423, 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 | 332,783,423 | |
| -1 | -332,783,423 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 332,783,423.
Example:
1 x 332,783,423 = 332,783,423
and
-1 x -332,783,423 = 332,783,423
Notice both answers equal 332,783,423
With that explanation out of the way, let's continue. Next, we take the number 332,783,423 and divide it by 2:
332,783,423 ÷ 2 = 166,391,711.5
If the quotient is a whole number, then 2 and 166,391,711.5 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 | 332,783,423 | |
| -1 | -332,783,423 |
Now, we try dividing 332,783,423 by 3:
332,783,423 ÷ 3 = 110,927,807.6667
If the quotient is a whole number, then 3 and 110,927,807.6667 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 | 332,783,423 | |
| -1 | -332,783,423 |
Let's try dividing by 4:
332,783,423 ÷ 4 = 83,195,855.75
If the quotient is a whole number, then 4 and 83,195,855.75 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 | 332,783,423 | |
| -1 | 332,783,423 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 59 | 133 | 413 | 1,121 | 7,847 | 42,409 | 296,863 | 805,771 | 2,502,131 | 5,640,397 | 17,514,917 | 47,540,489 | 332,783,423 |
| -1 | -7 | -19 | -59 | -133 | -413 | -1,121 | -7,847 | -42,409 | -296,863 | -805,771 | -2,502,131 | -5,640,397 | -17,514,917 | -47,540,489 | -332,783,423 |
