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 113,052,121, 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 | 113,052,121 | |
| -1 | -113,052,121 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 113,052,121.
Example:
1 x 113,052,121 = 113,052,121
and
-1 x -113,052,121 = 113,052,121
Notice both answers equal 113,052,121
With that explanation out of the way, let's continue. Next, we take the number 113,052,121 and divide it by 2:
113,052,121 ÷ 2 = 56,526,060.5
If the quotient is a whole number, then 2 and 56,526,060.5 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 | 113,052,121 | |
| -1 | -113,052,121 |
Now, we try dividing 113,052,121 by 3:
113,052,121 ÷ 3 = 37,684,040.3333
If the quotient is a whole number, then 3 and 37,684,040.3333 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 | 113,052,121 | |
| -1 | -113,052,121 |
Let's try dividing by 4:
113,052,121 ÷ 4 = 28,263,030.25
If the quotient is a whole number, then 4 and 28,263,030.25 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 | 113,052,121 | |
| -1 | 113,052,121 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 29 | 91 | 203 | 377 | 2,639 | 42,839 | 299,873 | 556,907 | 1,242,331 | 3,898,349 | 8,696,317 | 16,150,303 | 113,052,121 |
| -1 | -7 | -13 | -29 | -91 | -203 | -377 | -2,639 | -42,839 | -299,873 | -556,907 | -1,242,331 | -3,898,349 | -8,696,317 | -16,150,303 | -113,052,121 |
