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 124,440,215, 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 | 124,440,215 | |
| -1 | -124,440,215 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 124,440,215.
Example:
1 x 124,440,215 = 124,440,215
and
-1 x -124,440,215 = 124,440,215
Notice both answers equal 124,440,215
With that explanation out of the way, let's continue. Next, we take the number 124,440,215 and divide it by 2:
124,440,215 ÷ 2 = 62,220,107.5
If the quotient is a whole number, then 2 and 62,220,107.5 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 | 124,440,215 | |
| -1 | -124,440,215 |
Now, we try dividing 124,440,215 by 3:
124,440,215 ÷ 3 = 41,480,071.6667
If the quotient is a whole number, then 3 and 41,480,071.6667 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 | 124,440,215 | |
| -1 | -124,440,215 |
Let's try dividing by 4:
124,440,215 ÷ 4 = 31,110,053.75
If the quotient is a whole number, then 4 and 31,110,053.75 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 | 124,440,215 | |
| -1 | 124,440,215 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 95 | 181 | 905 | 3,439 | 7,237 | 17,195 | 36,185 | 137,503 | 687,515 | 1,309,897 | 6,549,485 | 24,888,043 | 124,440,215 |
| -1 | -5 | -19 | -95 | -181 | -905 | -3,439 | -7,237 | -17,195 | -36,185 | -137,503 | -687,515 | -1,309,897 | -6,549,485 | -24,888,043 | -124,440,215 |
