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 125,122,249, 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 | 125,122,249 | |
| -1 | -125,122,249 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 125,122,249.
Example:
1 x 125,122,249 = 125,122,249
and
-1 x -125,122,249 = 125,122,249
Notice both answers equal 125,122,249
With that explanation out of the way, let's continue. Next, we take the number 125,122,249 and divide it by 2:
125,122,249 ÷ 2 = 62,561,124.5
If the quotient is a whole number, then 2 and 62,561,124.5 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 | 125,122,249 | |
| -1 | -125,122,249 |
Now, we try dividing 125,122,249 by 3:
125,122,249 ÷ 3 = 41,707,416.3333
If the quotient is a whole number, then 3 and 41,707,416.3333 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 | 125,122,249 | |
| -1 | -125,122,249 |
Let's try dividing by 4:
125,122,249 ÷ 4 = 31,280,562.25
If the quotient is a whole number, then 4 and 31,280,562.25 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 | 125,122,249 | |
| -1 | 125,122,249 |
If you did it right, you will end up with this table:
| 1 | 7 | 157 | 257 | 443 | 1,099 | 1,799 | 3,101 | 40,349 | 69,551 | 113,851 | 282,443 | 486,857 | 796,957 | 17,874,607 | 125,122,249 |
| -1 | -7 | -157 | -257 | -443 | -1,099 | -1,799 | -3,101 | -40,349 | -69,551 | -113,851 | -282,443 | -486,857 | -796,957 | -17,874,607 | -125,122,249 |
