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 120,244,111, 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 | 120,244,111 | |
| -1 | -120,244,111 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 120,244,111.
Example:
1 x 120,244,111 = 120,244,111
and
-1 x -120,244,111 = 120,244,111
Notice both answers equal 120,244,111
With that explanation out of the way, let's continue. Next, we take the number 120,244,111 and divide it by 2:
120,244,111 ÷ 2 = 60,122,055.5
If the quotient is a whole number, then 2 and 60,122,055.5 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 | 120,244,111 | |
| -1 | -120,244,111 |
Now, we try dividing 120,244,111 by 3:
120,244,111 ÷ 3 = 40,081,370.3333
If the quotient is a whole number, then 3 and 40,081,370.3333 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 | 120,244,111 | |
| -1 | -120,244,111 |
Let's try dividing by 4:
120,244,111 ÷ 4 = 30,061,027.75
If the quotient is a whole number, then 4 and 30,061,027.75 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 | 120,244,111 | |
| -1 | 120,244,111 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 221 | 349 | 1,559 | 4,537 | 5,933 | 20,267 | 26,503 | 77,129 | 344,539 | 544,091 | 7,073,183 | 9,249,547 | 120,244,111 |
| -1 | -13 | -17 | -221 | -349 | -1,559 | -4,537 | -5,933 | -20,267 | -26,503 | -77,129 | -344,539 | -544,091 | -7,073,183 | -9,249,547 | -120,244,111 |
