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 330,300,305, 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 | 330,300,305 | |
| -1 | -330,300,305 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 330,300,305.
Example:
1 x 330,300,305 = 330,300,305
and
-1 x -330,300,305 = 330,300,305
Notice both answers equal 330,300,305
With that explanation out of the way, let's continue. Next, we take the number 330,300,305 and divide it by 2:
330,300,305 ÷ 2 = 165,150,152.5
If the quotient is a whole number, then 2 and 165,150,152.5 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 | 330,300,305 | |
| -1 | -330,300,305 |
Now, we try dividing 330,300,305 by 3:
330,300,305 ÷ 3 = 110,100,101.6667
If the quotient is a whole number, then 3 and 110,100,101.6667 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 | 330,300,305 | |
| -1 | -330,300,305 |
Let's try dividing by 4:
330,300,305 ÷ 4 = 82,575,076.25
If the quotient is a whole number, then 4 and 82,575,076.25 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 | 330,300,305 | |
| -1 | 330,300,305 |
If you did it right, you will end up with this table:
| 1 | 5 | 41 | 205 | 863 | 1,867 | 4,315 | 9,335 | 35,383 | 76,547 | 176,915 | 382,735 | 1,611,221 | 8,056,105 | 66,060,061 | 330,300,305 |
| -1 | -5 | -41 | -205 | -863 | -1,867 | -4,315 | -9,335 | -35,383 | -76,547 | -176,915 | -382,735 | -1,611,221 | -8,056,105 | -66,060,061 | -330,300,305 |
