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 120,610,219, 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 | 120,610,219 | |
| -1 | -120,610,219 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 120,610,219.
Example:
1 x 120,610,219 = 120,610,219
and
-1 x -120,610,219 = 120,610,219
Notice both answers equal 120,610,219
With that explanation out of the way, let's continue. Next, we take the number 120,610,219 and divide it by 2:
120,610,219 ÷ 2 = 60,305,109.5
If the quotient is a whole number, then 2 and 60,305,109.5 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 | 120,610,219 | |
| -1 | -120,610,219 |
Now, we try dividing 120,610,219 by 3:
120,610,219 ÷ 3 = 40,203,406.3333
If the quotient is a whole number, then 3 and 40,203,406.3333 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 | 120,610,219 | |
| -1 | -120,610,219 |
Let's try dividing by 4:
120,610,219 ÷ 4 = 30,152,554.75
If the quotient is a whole number, then 4 and 30,152,554.75 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 | 120,610,219 | |
| -1 | 120,610,219 |
If you did it right, you will end up with this table:
| 1 | 59 | 89 | 103 | 223 | 5,251 | 6,077 | 9,167 | 13,157 | 19,847 | 22,969 | 540,853 | 1,170,973 | 1,355,171 | 2,044,241 | 120,610,219 |
| -1 | -59 | -89 | -103 | -223 | -5,251 | -6,077 | -9,167 | -13,157 | -19,847 | -22,969 | -540,853 | -1,170,973 | -1,355,171 | -2,044,241 | -120,610,219 |
