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 320,011,027, 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 | 320,011,027 | |
| -1 | -320,011,027 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 320,011,027.
Example:
1 x 320,011,027 = 320,011,027
and
-1 x -320,011,027 = 320,011,027
Notice both answers equal 320,011,027
With that explanation out of the way, let's continue. Next, we take the number 320,011,027 and divide it by 2:
320,011,027 ÷ 2 = 160,005,513.5
If the quotient is a whole number, then 2 and 160,005,513.5 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 | 320,011,027 | |
| -1 | -320,011,027 |
Now, we try dividing 320,011,027 by 3:
320,011,027 ÷ 3 = 106,670,342.3333
If the quotient is a whole number, then 3 and 106,670,342.3333 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 | 320,011,027 | |
| -1 | -320,011,027 |
Let's try dividing by 4:
320,011,027 ÷ 4 = 80,002,756.75
If the quotient is a whole number, then 4 and 80,002,756.75 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 | 320,011,027 | |
| -1 | 320,011,027 |
If you did it right, you will end up with this table:
| 1 | 7 | 29 | 41 | 203 | 287 | 1,189 | 8,323 | 38,449 | 269,143 | 1,115,021 | 1,576,409 | 7,805,147 | 11,034,863 | 45,715,861 | 320,011,027 |
| -1 | -7 | -29 | -41 | -203 | -287 | -1,189 | -8,323 | -38,449 | -269,143 | -1,115,021 | -1,576,409 | -7,805,147 | -11,034,863 | -45,715,861 | -320,011,027 |
