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 330,395, 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 | 330,395 | |
| -1 | -330,395 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 330,395.
Example:
1 x 330,395 = 330,395
and
-1 x -330,395 = 330,395
Notice both answers equal 330,395
With that explanation out of the way, let's continue. Next, we take the number 330,395 and divide it by 2:
330,395 ÷ 2 = 165,197.5
If the quotient is a whole number, then 2 and 165,197.5 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 | 330,395 | |
| -1 | -330,395 |
Now, we try dividing 330,395 by 3:
330,395 ÷ 3 = 110,131.6667
If the quotient is a whole number, then 3 and 110,131.6667 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 | 330,395 | |
| -1 | -330,395 |
Let's try dividing by 4:
330,395 ÷ 4 = 82,598.75
If the quotient is a whole number, then 4 and 82,598.75 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 | 330,395 | |
| -1 | 330,395 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 17 | 23 | 65 | 85 | 115 | 169 | 221 | 299 | 391 | 845 | 1,105 | 1,495 | 1,955 | 2,873 | 3,887 | 5,083 | 14,365 | 19,435 | 25,415 | 66,079 | 330,395 |
| -1 | -5 | -13 | -17 | -23 | -65 | -85 | -115 | -169 | -221 | -299 | -391 | -845 | -1,105 | -1,495 | -1,955 | -2,873 | -3,887 | -5,083 | -14,365 | -19,435 | -25,415 | -66,079 | -330,395 |
