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 102,423,101, 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 | 102,423,101 | |
| -1 | -102,423,101 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 102,423,101.
Example:
1 x 102,423,101 = 102,423,101
and
-1 x -102,423,101 = 102,423,101
Notice both answers equal 102,423,101
With that explanation out of the way, let's continue. Next, we take the number 102,423,101 and divide it by 2:
102,423,101 ÷ 2 = 51,211,550.5
If the quotient is a whole number, then 2 and 51,211,550.5 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 | 102,423,101 | |
| -1 | -102,423,101 |
Now, we try dividing 102,423,101 by 3:
102,423,101 ÷ 3 = 34,141,033.6667
If the quotient is a whole number, then 3 and 34,141,033.6667 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 | 102,423,101 | |
| -1 | -102,423,101 |
Let's try dividing by 4:
102,423,101 ÷ 4 = 25,605,775.25
If the quotient is a whole number, then 4 and 25,605,775.25 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 | 102,423,101 | |
| -1 | 102,423,101 |
If you did it right, you will end up with this table:
| 1 | 11 | 31 | 67 | 341 | 737 | 2,077 | 4,483 | 22,847 | 49,313 | 138,973 | 300,361 | 1,528,703 | 3,303,971 | 9,311,191 | 102,423,101 |
| -1 | -11 | -31 | -67 | -341 | -737 | -2,077 | -4,483 | -22,847 | -49,313 | -138,973 | -300,361 | -1,528,703 | -3,303,971 | -9,311,191 | -102,423,101 |
