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 123,111,995, 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 | 123,111,995 | |
| -1 | -123,111,995 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 123,111,995.
Example:
1 x 123,111,995 = 123,111,995
and
-1 x -123,111,995 = 123,111,995
Notice both answers equal 123,111,995
With that explanation out of the way, let's continue. Next, we take the number 123,111,995 and divide it by 2:
123,111,995 ÷ 2 = 61,555,997.5
If the quotient is a whole number, then 2 and 61,555,997.5 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 | 123,111,995 | |
| -1 | -123,111,995 |
Now, we try dividing 123,111,995 by 3:
123,111,995 ÷ 3 = 41,037,331.6667
If the quotient is a whole number, then 3 and 41,037,331.6667 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 | 123,111,995 | |
| -1 | -123,111,995 |
Let's try dividing by 4:
123,111,995 ÷ 4 = 30,777,998.75
If the quotient is a whole number, then 4 and 30,777,998.75 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 | 123,111,995 | |
| -1 | 123,111,995 |
If you did it right, you will end up with this table:
| 1 | 5 | 149 | 257 | 643 | 745 | 1,285 | 3,215 | 38,293 | 95,807 | 165,251 | 191,465 | 479,035 | 826,255 | 24,622,399 | 123,111,995 |
| -1 | -5 | -149 | -257 | -643 | -745 | -1,285 | -3,215 | -38,293 | -95,807 | -165,251 | -191,465 | -479,035 | -826,255 | -24,622,399 | -123,111,995 |
