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 332,005,145, 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 | 332,005,145 | |
| -1 | -332,005,145 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 332,005,145.
Example:
1 x 332,005,145 = 332,005,145
and
-1 x -332,005,145 = 332,005,145
Notice both answers equal 332,005,145
With that explanation out of the way, let's continue. Next, we take the number 332,005,145 and divide it by 2:
332,005,145 ÷ 2 = 166,002,572.5
If the quotient is a whole number, then 2 and 166,002,572.5 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 | 332,005,145 | |
| -1 | -332,005,145 |
Now, we try dividing 332,005,145 by 3:
332,005,145 ÷ 3 = 110,668,381.6667
If the quotient is a whole number, then 3 and 110,668,381.6667 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 | 332,005,145 | |
| -1 | -332,005,145 |
Let's try dividing by 4:
332,005,145 ÷ 4 = 83,001,286.25
If the quotient is a whole number, then 4 and 83,001,286.25 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 | 332,005,145 | |
| -1 | 332,005,145 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 95 | 397 | 1,985 | 7,543 | 8,803 | 37,715 | 44,015 | 167,257 | 836,285 | 3,494,791 | 17,473,955 | 66,401,029 | 332,005,145 |
| -1 | -5 | -19 | -95 | -397 | -1,985 | -7,543 | -8,803 | -37,715 | -44,015 | -167,257 | -836,285 | -3,494,791 | -17,473,955 | -66,401,029 | -332,005,145 |
