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 120,181,867, 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 | 120,181,867 | |
| -1 | -120,181,867 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 120,181,867.
Example:
1 x 120,181,867 = 120,181,867
and
-1 x -120,181,867 = 120,181,867
Notice both answers equal 120,181,867
With that explanation out of the way, let's continue. Next, we take the number 120,181,867 and divide it by 2:
120,181,867 ÷ 2 = 60,090,933.5
If the quotient is a whole number, then 2 and 60,090,933.5 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 | 120,181,867 | |
| -1 | -120,181,867 |
Now, we try dividing 120,181,867 by 3:
120,181,867 ÷ 3 = 40,060,622.3333
If the quotient is a whole number, then 3 and 40,060,622.3333 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 | 120,181,867 | |
| -1 | -120,181,867 |
Let's try dividing by 4:
120,181,867 ÷ 4 = 30,045,466.75
If the quotient is a whole number, then 4 and 30,045,466.75 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 | 120,181,867 | |
| -1 | 120,181,867 |
If you did it right, you will end up with this table:
| 1 | 13 | 47 | 239 | 611 | 823 | 3,107 | 10,699 | 11,233 | 38,681 | 146,029 | 196,697 | 502,853 | 2,557,061 | 9,244,759 | 120,181,867 |
| -1 | -13 | -47 | -239 | -611 | -823 | -3,107 | -10,699 | -11,233 | -38,681 | -146,029 | -196,697 | -502,853 | -2,557,061 | -9,244,759 | -120,181,867 |
