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 121,034,255, 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 | 121,034,255 | |
| -1 | -121,034,255 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 121,034,255.
Example:
1 x 121,034,255 = 121,034,255
and
-1 x -121,034,255 = 121,034,255
Notice both answers equal 121,034,255
With that explanation out of the way, let's continue. Next, we take the number 121,034,255 and divide it by 2:
121,034,255 ÷ 2 = 60,517,127.5
If the quotient is a whole number, then 2 and 60,517,127.5 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 | 121,034,255 | |
| -1 | -121,034,255 |
Now, we try dividing 121,034,255 by 3:
121,034,255 ÷ 3 = 40,344,751.6667
If the quotient is a whole number, then 3 and 40,344,751.6667 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 | 121,034,255 | |
| -1 | -121,034,255 |
Let's try dividing by 4:
121,034,255 ÷ 4 = 30,258,563.75
If the quotient is a whole number, then 4 and 30,258,563.75 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 | 121,034,255 | |
| -1 | 121,034,255 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 41 | 145 | 205 | 1,189 | 5,945 | 20,359 | 101,795 | 590,411 | 834,719 | 2,952,055 | 4,173,595 | 24,206,851 | 121,034,255 |
| -1 | -5 | -29 | -41 | -145 | -205 | -1,189 | -5,945 | -20,359 | -101,795 | -590,411 | -834,719 | -2,952,055 | -4,173,595 | -24,206,851 | -121,034,255 |
