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 113,241,121, 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 | 113,241,121 | |
| -1 | -113,241,121 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 113,241,121.
Example:
1 x 113,241,121 = 113,241,121
and
-1 x -113,241,121 = 113,241,121
Notice both answers equal 113,241,121
With that explanation out of the way, let's continue. Next, we take the number 113,241,121 and divide it by 2:
113,241,121 ÷ 2 = 56,620,560.5
If the quotient is a whole number, then 2 and 56,620,560.5 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 | 113,241,121 | |
| -1 | -113,241,121 |
Now, we try dividing 113,241,121 by 3:
113,241,121 ÷ 3 = 37,747,040.3333
If the quotient is a whole number, then 3 and 37,747,040.3333 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 | 113,241,121 | |
| -1 | -113,241,121 |
Let's try dividing by 4:
113,241,121 ÷ 4 = 28,310,280.25
If the quotient is a whole number, then 4 and 28,310,280.25 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 | 113,241,121 | |
| -1 | 113,241,121 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 23 | 133 | 161 | 437 | 3,059 | 37,019 | 259,133 | 703,361 | 851,437 | 4,923,527 | 5,960,059 | 16,177,303 | 113,241,121 |
| -1 | -7 | -19 | -23 | -133 | -161 | -437 | -3,059 | -37,019 | -259,133 | -703,361 | -851,437 | -4,923,527 | -5,960,059 | -16,177,303 | -113,241,121 |
