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 120,580,735, 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 | 120,580,735 | |
| -1 | -120,580,735 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 120,580,735.
Example:
1 x 120,580,735 = 120,580,735
and
-1 x -120,580,735 = 120,580,735
Notice both answers equal 120,580,735
With that explanation out of the way, let's continue. Next, we take the number 120,580,735 and divide it by 2:
120,580,735 ÷ 2 = 60,290,367.5
If the quotient is a whole number, then 2 and 60,290,367.5 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 | 120,580,735 | |
| -1 | -120,580,735 |
Now, we try dividing 120,580,735 by 3:
120,580,735 ÷ 3 = 40,193,578.3333
If the quotient is a whole number, then 3 and 40,193,578.3333 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 | 120,580,735 | |
| -1 | -120,580,735 |
Let's try dividing by 4:
120,580,735 ÷ 4 = 30,145,183.75
If the quotient is a whole number, then 4 and 30,145,183.75 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 | 120,580,735 | |
| -1 | 120,580,735 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 121 | 241 | 605 | 827 | 1,205 | 2,651 | 4,135 | 9,097 | 13,255 | 29,161 | 45,485 | 100,067 | 145,805 | 199,307 | 500,335 | 996,535 | 2,192,377 | 10,961,885 | 24,116,147 | 120,580,735 |
| -1 | -5 | -11 | -55 | -121 | -241 | -605 | -827 | -1,205 | -2,651 | -4,135 | -9,097 | -13,255 | -29,161 | -45,485 | -100,067 | -145,805 | -199,307 | -500,335 | -996,535 | -2,192,377 | -10,961,885 | -24,116,147 | -120,580,735 |
