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 242,243,123, 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 | 242,243,123 | |
| -1 | -242,243,123 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 242,243,123.
Example:
1 x 242,243,123 = 242,243,123
and
-1 x -242,243,123 = 242,243,123
Notice both answers equal 242,243,123
With that explanation out of the way, let's continue. Next, we take the number 242,243,123 and divide it by 2:
242,243,123 ÷ 2 = 121,121,561.5
If the quotient is a whole number, then 2 and 121,121,561.5 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 | 242,243,123 | |
| -1 | -242,243,123 |
Now, we try dividing 242,243,123 by 3:
242,243,123 ÷ 3 = 80,747,707.6667
If the quotient is a whole number, then 3 and 80,747,707.6667 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 | 242,243,123 | |
| -1 | -242,243,123 |
Let's try dividing by 4:
242,243,123 ÷ 4 = 60,560,780.75
If the quotient is a whole number, then 4 and 60,560,780.75 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 | 242,243,123 | |
| -1 | 242,243,123 |
If you did it right, you will end up with this table:
| 1 | 43 | 47 | 67 | 1,789 | 2,021 | 2,881 | 3,149 | 76,927 | 84,083 | 119,863 | 135,407 | 3,615,569 | 5,154,109 | 5,633,561 | 242,243,123 |
| -1 | -43 | -47 | -67 | -1,789 | -2,021 | -2,881 | -3,149 | -76,927 | -84,083 | -119,863 | -135,407 | -3,615,569 | -5,154,109 | -5,633,561 | -242,243,123 |
