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 125,332,405, 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 | 125,332,405 | |
| -1 | -125,332,405 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 125,332,405.
Example:
1 x 125,332,405 = 125,332,405
and
-1 x -125,332,405 = 125,332,405
Notice both answers equal 125,332,405
With that explanation out of the way, let's continue. Next, we take the number 125,332,405 and divide it by 2:
125,332,405 ÷ 2 = 62,666,202.5
If the quotient is a whole number, then 2 and 62,666,202.5 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 | 125,332,405 | |
| -1 | -125,332,405 |
Now, we try dividing 125,332,405 by 3:
125,332,405 ÷ 3 = 41,777,468.3333
If the quotient is a whole number, then 3 and 41,777,468.3333 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 | 125,332,405 | |
| -1 | -125,332,405 |
Let's try dividing by 4:
125,332,405 ÷ 4 = 31,333,101.25
If the quotient is a whole number, then 4 and 31,333,101.25 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 | 125,332,405 | |
| -1 | 125,332,405 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 23 | 55 | 115 | 121 | 253 | 605 | 1,265 | 2,783 | 9,007 | 13,915 | 45,035 | 99,077 | 207,161 | 495,385 | 1,035,805 | 1,089,847 | 2,278,771 | 5,449,235 | 11,393,855 | 25,066,481 | 125,332,405 |
| -1 | -5 | -11 | -23 | -55 | -115 | -121 | -253 | -605 | -1,265 | -2,783 | -9,007 | -13,915 | -45,035 | -99,077 | -207,161 | -495,385 | -1,035,805 | -1,089,847 | -2,278,771 | -5,449,235 | -11,393,855 | -25,066,481 | -125,332,405 |
