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 122,003,305, 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 | 122,003,305 | |
| -1 | -122,003,305 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 122,003,305.
Example:
1 x 122,003,305 = 122,003,305
and
-1 x -122,003,305 = 122,003,305
Notice both answers equal 122,003,305
With that explanation out of the way, let's continue. Next, we take the number 122,003,305 and divide it by 2:
122,003,305 ÷ 2 = 61,001,652.5
If the quotient is a whole number, then 2 and 61,001,652.5 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 | 122,003,305 | |
| -1 | -122,003,305 |
Now, we try dividing 122,003,305 by 3:
122,003,305 ÷ 3 = 40,667,768.3333
If the quotient is a whole number, then 3 and 40,667,768.3333 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 | 122,003,305 | |
| -1 | -122,003,305 |
Let's try dividing by 4:
122,003,305 ÷ 4 = 30,500,826.25
If the quotient is a whole number, then 4 and 30,500,826.25 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 | 122,003,305 | |
| -1 | 122,003,305 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 47 | 85 | 235 | 799 | 3,995 | 30,539 | 152,695 | 519,163 | 1,435,333 | 2,595,815 | 7,176,665 | 24,400,661 | 122,003,305 |
| -1 | -5 | -17 | -47 | -85 | -235 | -799 | -3,995 | -30,539 | -152,695 | -519,163 | -1,435,333 | -2,595,815 | -7,176,665 | -24,400,661 | -122,003,305 |
