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 120,775,633, 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 | 120,775,633 | |
| -1 | -120,775,633 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 120,775,633.
Example:
1 x 120,775,633 = 120,775,633
and
-1 x -120,775,633 = 120,775,633
Notice both answers equal 120,775,633
With that explanation out of the way, let's continue. Next, we take the number 120,775,633 and divide it by 2:
120,775,633 ÷ 2 = 60,387,816.5
If the quotient is a whole number, then 2 and 60,387,816.5 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 | 120,775,633 | |
| -1 | -120,775,633 |
Now, we try dividing 120,775,633 by 3:
120,775,633 ÷ 3 = 40,258,544.3333
If the quotient is a whole number, then 3 and 40,258,544.3333 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 | 120,775,633 | |
| -1 | -120,775,633 |
Let's try dividing by 4:
120,775,633 ÷ 4 = 30,193,908.25
If the quotient is a whole number, then 4 and 30,193,908.25 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 | 120,775,633 | |
| -1 | 120,775,633 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 29 | 187 | 319 | 493 | 5,423 | 22,271 | 244,981 | 378,607 | 645,859 | 4,164,677 | 7,104,449 | 10,979,603 | 120,775,633 |
| -1 | -11 | -17 | -29 | -187 | -319 | -493 | -5,423 | -22,271 | -244,981 | -378,607 | -645,859 | -4,164,677 | -7,104,449 | -10,979,603 | -120,775,633 |
