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 124,211,099, 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 | 124,211,099 | |
| -1 | -124,211,099 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 124,211,099.
Example:
1 x 124,211,099 = 124,211,099
and
-1 x -124,211,099 = 124,211,099
Notice both answers equal 124,211,099
With that explanation out of the way, let's continue. Next, we take the number 124,211,099 and divide it by 2:
124,211,099 ÷ 2 = 62,105,549.5
If the quotient is a whole number, then 2 and 62,105,549.5 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 | 124,211,099 | |
| -1 | -124,211,099 |
Now, we try dividing 124,211,099 by 3:
124,211,099 ÷ 3 = 41,403,699.6667
If the quotient is a whole number, then 3 and 41,403,699.6667 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 | 124,211,099 | |
| -1 | -124,211,099 |
Let's try dividing by 4:
124,211,099 ÷ 4 = 31,052,774.75
If the quotient is a whole number, then 4 and 31,052,774.75 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 | 124,211,099 | |
| -1 | 124,211,099 |
If you did it right, you will end up with this table:
| 1 | 41 | 67 | 103 | 439 | 2,747 | 4,223 | 6,901 | 17,999 | 29,413 | 45,217 | 282,941 | 1,205,933 | 1,853,897 | 3,029,539 | 124,211,099 |
| -1 | -41 | -67 | -103 | -439 | -2,747 | -4,223 | -6,901 | -17,999 | -29,413 | -45,217 | -282,941 | -1,205,933 | -1,853,897 | -3,029,539 | -124,211,099 |
