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 120,063,289, 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 | 120,063,289 | |
| -1 | -120,063,289 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 120,063,289.
Example:
1 x 120,063,289 = 120,063,289
and
-1 x -120,063,289 = 120,063,289
Notice both answers equal 120,063,289
With that explanation out of the way, let's continue. Next, we take the number 120,063,289 and divide it by 2:
120,063,289 ÷ 2 = 60,031,644.5
If the quotient is a whole number, then 2 and 60,031,644.5 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 | 120,063,289 | |
| -1 | -120,063,289 |
Now, we try dividing 120,063,289 by 3:
120,063,289 ÷ 3 = 40,021,096.3333
If the quotient is a whole number, then 3 and 40,021,096.3333 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 | 120,063,289 | |
| -1 | -120,063,289 |
Let's try dividing by 4:
120,063,289 ÷ 4 = 30,015,822.25
If the quotient is a whole number, then 4 and 30,015,822.25 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 | 120,063,289 | |
| -1 | 120,063,289 |
If you did it right, you will end up with this table:
| 1 | 23 | 59 | 103 | 859 | 1,357 | 2,369 | 6,077 | 19,757 | 50,681 | 88,477 | 139,771 | 1,165,663 | 2,034,971 | 5,220,143 | 120,063,289 |
| -1 | -23 | -59 | -103 | -859 | -1,357 | -2,369 | -6,077 | -19,757 | -50,681 | -88,477 | -139,771 | -1,165,663 | -2,034,971 | -5,220,143 | -120,063,289 |
