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 332,006,185, 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 | 332,006,185 | |
| -1 | -332,006,185 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 332,006,185.
Example:
1 x 332,006,185 = 332,006,185
and
-1 x -332,006,185 = 332,006,185
Notice both answers equal 332,006,185
With that explanation out of the way, let's continue. Next, we take the number 332,006,185 and divide it by 2:
332,006,185 ÷ 2 = 166,003,092.5
If the quotient is a whole number, then 2 and 166,003,092.5 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 | 332,006,185 | |
| -1 | -332,006,185 |
Now, we try dividing 332,006,185 by 3:
332,006,185 ÷ 3 = 110,668,728.3333
If the quotient is a whole number, then 3 and 110,668,728.3333 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 | 332,006,185 | |
| -1 | -332,006,185 |
Let's try dividing by 4:
332,006,185 ÷ 4 = 83,001,546.25
If the quotient is a whole number, then 4 and 83,001,546.25 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 | 332,006,185 | |
| -1 | 332,006,185 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 2,221 | 4,271 | 11,105 | 15,547 | 21,355 | 29,897 | 77,735 | 149,485 | 9,485,891 | 47,429,455 | 66,401,237 | 332,006,185 |
| -1 | -5 | -7 | -35 | -2,221 | -4,271 | -11,105 | -15,547 | -21,355 | -29,897 | -77,735 | -149,485 | -9,485,891 | -47,429,455 | -66,401,237 | -332,006,185 |
