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 120,067,705, 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 | 120,067,705 | |
| -1 | -120,067,705 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 120,067,705.
Example:
1 x 120,067,705 = 120,067,705
and
-1 x -120,067,705 = 120,067,705
Notice both answers equal 120,067,705
With that explanation out of the way, let's continue. Next, we take the number 120,067,705 and divide it by 2:
120,067,705 ÷ 2 = 60,033,852.5
If the quotient is a whole number, then 2 and 60,033,852.5 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 | 120,067,705 | |
| -1 | -120,067,705 |
Now, we try dividing 120,067,705 by 3:
120,067,705 ÷ 3 = 40,022,568.3333
If the quotient is a whole number, then 3 and 40,022,568.3333 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 | 120,067,705 | |
| -1 | -120,067,705 |
Let's try dividing by 4:
120,067,705 ÷ 4 = 30,016,926.25
If the quotient is a whole number, then 4 and 30,016,926.25 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 | 120,067,705 | |
| -1 | 120,067,705 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 115 | 127 | 635 | 2,921 | 8,221 | 14,605 | 41,105 | 189,083 | 945,415 | 1,044,067 | 5,220,335 | 24,013,541 | 120,067,705 |
| -1 | -5 | -23 | -115 | -127 | -635 | -2,921 | -8,221 | -14,605 | -41,105 | -189,083 | -945,415 | -1,044,067 | -5,220,335 | -24,013,541 | -120,067,705 |
