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 123,557,495, 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 | 123,557,495 | |
| -1 | -123,557,495 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 123,557,495.
Example:
1 x 123,557,495 = 123,557,495
and
-1 x -123,557,495 = 123,557,495
Notice both answers equal 123,557,495
With that explanation out of the way, let's continue. Next, we take the number 123,557,495 and divide it by 2:
123,557,495 ÷ 2 = 61,778,747.5
If the quotient is a whole number, then 2 and 61,778,747.5 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 | 123,557,495 | |
| -1 | -123,557,495 |
Now, we try dividing 123,557,495 by 3:
123,557,495 ÷ 3 = 41,185,831.6667
If the quotient is a whole number, then 3 and 41,185,831.6667 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 | 123,557,495 | |
| -1 | -123,557,495 |
Let's try dividing by 4:
123,557,495 ÷ 4 = 30,889,373.75
If the quotient is a whole number, then 4 and 30,889,373.75 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 | 123,557,495 | |
| -1 | 123,557,495 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 109 | 115 | 545 | 2,507 | 9,857 | 12,535 | 49,285 | 226,711 | 1,074,413 | 1,133,555 | 5,372,065 | 24,711,499 | 123,557,495 |
| -1 | -5 | -23 | -109 | -115 | -545 | -2,507 | -9,857 | -12,535 | -49,285 | -226,711 | -1,074,413 | -1,133,555 | -5,372,065 | -24,711,499 | -123,557,495 |
