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 330,018,725, 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 | 330,018,725 | |
| -1 | -330,018,725 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 330,018,725.
Example:
1 x 330,018,725 = 330,018,725
and
-1 x -330,018,725 = 330,018,725
Notice both answers equal 330,018,725
With that explanation out of the way, let's continue. Next, we take the number 330,018,725 and divide it by 2:
330,018,725 ÷ 2 = 165,009,362.5
If the quotient is a whole number, then 2 and 165,009,362.5 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 | 330,018,725 | |
| -1 | -330,018,725 |
Now, we try dividing 330,018,725 by 3:
330,018,725 ÷ 3 = 110,006,241.6667
If the quotient is a whole number, then 3 and 110,006,241.6667 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 | 330,018,725 | |
| -1 | -330,018,725 |
Let's try dividing by 4:
330,018,725 ÷ 4 = 82,504,681.25
If the quotient is a whole number, then 4 and 82,504,681.25 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 | 330,018,725 | |
| -1 | 330,018,725 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 37 | 47 | 185 | 235 | 925 | 1,175 | 1,739 | 7,591 | 8,695 | 37,955 | 43,475 | 189,775 | 280,867 | 356,777 | 1,404,335 | 1,783,885 | 7,021,675 | 8,919,425 | 13,200,749 | 66,003,745 | 330,018,725 |
| -1 | -5 | -25 | -37 | -47 | -185 | -235 | -925 | -1,175 | -1,739 | -7,591 | -8,695 | -37,955 | -43,475 | -189,775 | -280,867 | -356,777 | -1,404,335 | -1,783,885 | -7,021,675 | -8,919,425 | -13,200,749 | -66,003,745 | -330,018,725 |
