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 121,233,023, 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 | 121,233,023 | |
| -1 | -121,233,023 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 121,233,023.
Example:
1 x 121,233,023 = 121,233,023
and
-1 x -121,233,023 = 121,233,023
Notice both answers equal 121,233,023
With that explanation out of the way, let's continue. Next, we take the number 121,233,023 and divide it by 2:
121,233,023 ÷ 2 = 60,616,511.5
If the quotient is a whole number, then 2 and 60,616,511.5 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 | 121,233,023 | |
| -1 | -121,233,023 |
Now, we try dividing 121,233,023 by 3:
121,233,023 ÷ 3 = 40,411,007.6667
If the quotient is a whole number, then 3 and 40,411,007.6667 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 | 121,233,023 | |
| -1 | -121,233,023 |
Let's try dividing by 4:
121,233,023 ÷ 4 = 30,308,255.75
If the quotient is a whole number, then 4 and 30,308,255.75 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 | 121,233,023 | |
| -1 | 121,233,023 |
If you did it right, you will end up with this table:
| 1 | 23 | 41 | 59 | 943 | 1,357 | 2,179 | 2,419 | 50,117 | 55,637 | 89,339 | 128,561 | 2,054,797 | 2,956,903 | 5,271,001 | 121,233,023 |
| -1 | -23 | -41 | -59 | -943 | -1,357 | -2,179 | -2,419 | -50,117 | -55,637 | -89,339 | -128,561 | -2,054,797 | -2,956,903 | -5,271,001 | -121,233,023 |
