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 120,065,825, 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 | 120,065,825 | |
| -1 | -120,065,825 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 120,065,825.
Example:
1 x 120,065,825 = 120,065,825
and
-1 x -120,065,825 = 120,065,825
Notice both answers equal 120,065,825
With that explanation out of the way, let's continue. Next, we take the number 120,065,825 and divide it by 2:
120,065,825 ÷ 2 = 60,032,912.5
If the quotient is a whole number, then 2 and 60,032,912.5 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 | 120,065,825 | |
| -1 | -120,065,825 |
Now, we try dividing 120,065,825 by 3:
120,065,825 ÷ 3 = 40,021,941.6667
If the quotient is a whole number, then 3 and 40,021,941.6667 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 | 120,065,825 | |
| -1 | -120,065,825 |
Let's try dividing by 4:
120,065,825 ÷ 4 = 30,016,456.25
If the quotient is a whole number, then 4 and 30,016,456.25 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 | 120,065,825 | |
| -1 | 120,065,825 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 55 | 275 | 431 | 1,013 | 2,155 | 4,741 | 5,065 | 10,775 | 11,143 | 23,705 | 25,325 | 55,715 | 118,525 | 278,575 | 436,603 | 2,183,015 | 4,802,633 | 10,915,075 | 24,013,165 | 120,065,825 |
| -1 | -5 | -11 | -25 | -55 | -275 | -431 | -1,013 | -2,155 | -4,741 | -5,065 | -10,775 | -11,143 | -23,705 | -25,325 | -55,715 | -118,525 | -278,575 | -436,603 | -2,183,015 | -4,802,633 | -10,915,075 | -24,013,165 | -120,065,825 |
