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 120,505,063, 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 | 120,505,063 | |
| -1 | -120,505,063 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 120,505,063.
Example:
1 x 120,505,063 = 120,505,063
and
-1 x -120,505,063 = 120,505,063
Notice both answers equal 120,505,063
With that explanation out of the way, let's continue. Next, we take the number 120,505,063 and divide it by 2:
120,505,063 ÷ 2 = 60,252,531.5
If the quotient is a whole number, then 2 and 60,252,531.5 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 | 120,505,063 | |
| -1 | -120,505,063 |
Now, we try dividing 120,505,063 by 3:
120,505,063 ÷ 3 = 40,168,354.3333
If the quotient is a whole number, then 3 and 40,168,354.3333 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 | 120,505,063 | |
| -1 | -120,505,063 |
Let's try dividing by 4:
120,505,063 ÷ 4 = 30,126,265.75
If the quotient is a whole number, then 4 and 30,126,265.75 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 | 120,505,063 | |
| -1 | 120,505,063 |
If you did it right, you will end up with this table:
| 1 | 7 | 29 | 49 | 137 | 203 | 619 | 959 | 1,421 | 3,973 | 4,333 | 6,713 | 17,951 | 27,811 | 30,331 | 84,803 | 125,657 | 194,677 | 593,621 | 879,599 | 2,459,287 | 4,155,347 | 17,215,009 | 120,505,063 |
| -1 | -7 | -29 | -49 | -137 | -203 | -619 | -959 | -1,421 | -3,973 | -4,333 | -6,713 | -17,951 | -27,811 | -30,331 | -84,803 | -125,657 | -194,677 | -593,621 | -879,599 | -2,459,287 | -4,155,347 | -17,215,009 | -120,505,063 |
