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 124,234,205, 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 | 124,234,205 | |
| -1 | -124,234,205 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 124,234,205.
Example:
1 x 124,234,205 = 124,234,205
and
-1 x -124,234,205 = 124,234,205
Notice both answers equal 124,234,205
With that explanation out of the way, let's continue. Next, we take the number 124,234,205 and divide it by 2:
124,234,205 ÷ 2 = 62,117,102.5
If the quotient is a whole number, then 2 and 62,117,102.5 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 | 124,234,205 | |
| -1 | -124,234,205 |
Now, we try dividing 124,234,205 by 3:
124,234,205 ÷ 3 = 41,411,401.6667
If the quotient is a whole number, then 3 and 41,411,401.6667 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 | 124,234,205 | |
| -1 | -124,234,205 |
Let's try dividing by 4:
124,234,205 ÷ 4 = 31,058,551.25
If the quotient is a whole number, then 4 and 31,058,551.25 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 | 124,234,205 | |
| -1 | 124,234,205 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 97 | 155 | 485 | 3,007 | 8,263 | 15,035 | 41,315 | 256,153 | 801,511 | 1,280,765 | 4,007,555 | 24,846,841 | 124,234,205 |
| -1 | -5 | -31 | -97 | -155 | -485 | -3,007 | -8,263 | -15,035 | -41,315 | -256,153 | -801,511 | -1,280,765 | -4,007,555 | -24,846,841 | -124,234,205 |
