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 123,305,735, 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 | 123,305,735 | |
| -1 | -123,305,735 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 123,305,735.
Example:
1 x 123,305,735 = 123,305,735
and
-1 x -123,305,735 = 123,305,735
Notice both answers equal 123,305,735
With that explanation out of the way, let's continue. Next, we take the number 123,305,735 and divide it by 2:
123,305,735 ÷ 2 = 61,652,867.5
If the quotient is a whole number, then 2 and 61,652,867.5 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 | 123,305,735 | |
| -1 | -123,305,735 |
Now, we try dividing 123,305,735 by 3:
123,305,735 ÷ 3 = 41,101,911.6667
If the quotient is a whole number, then 3 and 41,101,911.6667 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 | 123,305,735 | |
| -1 | -123,305,735 |
Let's try dividing by 4:
123,305,735 ÷ 4 = 30,826,433.75
If the quotient is a whole number, then 4 and 30,826,433.75 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 | 123,305,735 | |
| -1 | 123,305,735 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 709 | 3,545 | 4,963 | 4,969 | 24,815 | 24,845 | 34,783 | 173,915 | 3,523,021 | 17,615,105 | 24,661,147 | 123,305,735 |
| -1 | -5 | -7 | -35 | -709 | -3,545 | -4,963 | -4,969 | -24,815 | -24,845 | -34,783 | -173,915 | -3,523,021 | -17,615,105 | -24,661,147 | -123,305,735 |
