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 122,507,333, 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 | 122,507,333 | |
| -1 | -122,507,333 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 122,507,333.
Example:
1 x 122,507,333 = 122,507,333
and
-1 x -122,507,333 = 122,507,333
Notice both answers equal 122,507,333
With that explanation out of the way, let's continue. Next, we take the number 122,507,333 and divide it by 2:
122,507,333 ÷ 2 = 61,253,666.5
If the quotient is a whole number, then 2 and 61,253,666.5 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 | 122,507,333 | |
| -1 | -122,507,333 |
Now, we try dividing 122,507,333 by 3:
122,507,333 ÷ 3 = 40,835,777.6667
If the quotient is a whole number, then 3 and 40,835,777.6667 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 | 122,507,333 | |
| -1 | -122,507,333 |
Let's try dividing by 4:
122,507,333 ÷ 4 = 30,626,833.25
If the quotient is a whole number, then 4 and 30,626,833.25 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 | 122,507,333 | |
| -1 | 122,507,333 |
If you did it right, you will end up with this table:
| 1 | 13 | 37 | 47 | 481 | 611 | 1,739 | 5,419 | 22,607 | 70,447 | 200,503 | 254,693 | 2,606,539 | 3,311,009 | 9,423,641 | 122,507,333 |
| -1 | -13 | -37 | -47 | -481 | -611 | -1,739 | -5,419 | -22,607 | -70,447 | -200,503 | -254,693 | -2,606,539 | -3,311,009 | -9,423,641 | -122,507,333 |
