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 330,422,105, 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 | 330,422,105 | |
| -1 | -330,422,105 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 330,422,105.
Example:
1 x 330,422,105 = 330,422,105
and
-1 x -330,422,105 = 330,422,105
Notice both answers equal 330,422,105
With that explanation out of the way, let's continue. Next, we take the number 330,422,105 and divide it by 2:
330,422,105 ÷ 2 = 165,211,052.5
If the quotient is a whole number, then 2 and 165,211,052.5 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 | 330,422,105 | |
| -1 | -330,422,105 |
Now, we try dividing 330,422,105 by 3:
330,422,105 ÷ 3 = 110,140,701.6667
If the quotient is a whole number, then 3 and 110,140,701.6667 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 | 330,422,105 | |
| -1 | -330,422,105 |
Let's try dividing by 4:
330,422,105 ÷ 4 = 82,605,526.25
If the quotient is a whole number, then 4 and 82,605,526.25 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 | 330,422,105 | |
| -1 | 330,422,105 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 43 | 65 | 215 | 559 | 2,795 | 118,219 | 591,095 | 1,536,847 | 5,083,417 | 7,684,235 | 25,417,085 | 66,084,421 | 330,422,105 |
| -1 | -5 | -13 | -43 | -65 | -215 | -559 | -2,795 | -118,219 | -591,095 | -1,536,847 | -5,083,417 | -7,684,235 | -25,417,085 | -66,084,421 | -330,422,105 |
