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 122,328,271, 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 | 122,328,271 | |
| -1 | -122,328,271 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 122,328,271.
Example:
1 x 122,328,271 = 122,328,271
and
-1 x -122,328,271 = 122,328,271
Notice both answers equal 122,328,271
With that explanation out of the way, let's continue. Next, we take the number 122,328,271 and divide it by 2:
122,328,271 ÷ 2 = 61,164,135.5
If the quotient is a whole number, then 2 and 61,164,135.5 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 | 122,328,271 | |
| -1 | -122,328,271 |
Now, we try dividing 122,328,271 by 3:
122,328,271 ÷ 3 = 40,776,090.3333
If the quotient is a whole number, then 3 and 40,776,090.3333 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 | 122,328,271 | |
| -1 | -122,328,271 |
Let's try dividing by 4:
122,328,271 ÷ 4 = 30,582,067.75
If the quotient is a whole number, then 4 and 30,582,067.75 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 | 122,328,271 | |
| -1 | 122,328,271 |
If you did it right, you will end up with this table:
| 1 | 13 | 101 | 151 | 617 | 1,313 | 1,963 | 8,021 | 15,251 | 62,317 | 93,167 | 198,263 | 810,121 | 1,211,171 | 9,409,867 | 122,328,271 |
| -1 | -13 | -101 | -151 | -617 | -1,313 | -1,963 | -8,021 | -15,251 | -62,317 | -93,167 | -198,263 | -810,121 | -1,211,171 | -9,409,867 | -122,328,271 |
