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 121,840,241, 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 | 121,840,241 | |
| -1 | -121,840,241 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 121,840,241.
Example:
1 x 121,840,241 = 121,840,241
and
-1 x -121,840,241 = 121,840,241
Notice both answers equal 121,840,241
With that explanation out of the way, let's continue. Next, we take the number 121,840,241 and divide it by 2:
121,840,241 ÷ 2 = 60,920,120.5
If the quotient is a whole number, then 2 and 60,920,120.5 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 | 121,840,241 | |
| -1 | -121,840,241 |
Now, we try dividing 121,840,241 by 3:
121,840,241 ÷ 3 = 40,613,413.6667
If the quotient is a whole number, then 3 and 40,613,413.6667 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 | 121,840,241 | |
| -1 | -121,840,241 |
Let's try dividing by 4:
121,840,241 ÷ 4 = 30,460,060.25
If the quotient is a whole number, then 4 and 30,460,060.25 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 | 121,840,241 | |
| -1 | 121,840,241 |
If you did it right, you will end up with this table:
| 1 | 17 | 61 | 293 | 401 | 1,037 | 4,981 | 6,817 | 17,873 | 24,461 | 117,493 | 303,841 | 415,837 | 1,997,381 | 7,167,073 | 121,840,241 |
| -1 | -17 | -61 | -293 | -401 | -1,037 | -4,981 | -6,817 | -17,873 | -24,461 | -117,493 | -303,841 | -415,837 | -1,997,381 | -7,167,073 | -121,840,241 |
