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 330,251,351, 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 | 330,251,351 | |
| -1 | -330,251,351 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 330,251,351.
Example:
1 x 330,251,351 = 330,251,351
and
-1 x -330,251,351 = 330,251,351
Notice both answers equal 330,251,351
With that explanation out of the way, let's continue. Next, we take the number 330,251,351 and divide it by 2:
330,251,351 ÷ 2 = 165,125,675.5
If the quotient is a whole number, then 2 and 165,125,675.5 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 | 330,251,351 | |
| -1 | -330,251,351 |
Now, we try dividing 330,251,351 by 3:
330,251,351 ÷ 3 = 110,083,783.6667
If the quotient is a whole number, then 3 and 110,083,783.6667 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 | 330,251,351 | |
| -1 | -330,251,351 |
Let's try dividing by 4:
330,251,351 ÷ 4 = 82,562,837.75
If the quotient is a whole number, then 4 and 82,562,837.75 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 | 330,251,351 | |
| -1 | 330,251,351 |
If you did it right, you will end up with this table:
| 1 | 41 | 139 | 167 | 347 | 5,699 | 6,847 | 14,227 | 23,213 | 48,233 | 57,949 | 951,733 | 1,977,553 | 2,375,909 | 8,054,911 | 330,251,351 |
| -1 | -41 | -139 | -167 | -347 | -5,699 | -6,847 | -14,227 | -23,213 | -48,233 | -57,949 | -951,733 | -1,977,553 | -2,375,909 | -8,054,911 | -330,251,351 |
