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 327,300,127, 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 | 327,300,127 | |
| -1 | -327,300,127 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 327,300,127.
Example:
1 x 327,300,127 = 327,300,127
and
-1 x -327,300,127 = 327,300,127
Notice both answers equal 327,300,127
With that explanation out of the way, let's continue. Next, we take the number 327,300,127 and divide it by 2:
327,300,127 ÷ 2 = 163,650,063.5
If the quotient is a whole number, then 2 and 163,650,063.5 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 | 327,300,127 | |
| -1 | -327,300,127 |
Now, we try dividing 327,300,127 by 3:
327,300,127 ÷ 3 = 109,100,042.3333
If the quotient is a whole number, then 3 and 109,100,042.3333 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 | 327,300,127 | |
| -1 | -327,300,127 |
Let's try dividing by 4:
327,300,127 ÷ 4 = 81,825,031.75
If the quotient is a whole number, then 4 and 81,825,031.75 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 | 327,300,127 | |
| -1 | 327,300,127 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 167 | 1,169 | 1,837 | 12,859 | 25,453 | 178,171 | 279,983 | 1,959,881 | 4,250,651 | 29,754,557 | 46,757,161 | 327,300,127 |
| -1 | -7 | -11 | -77 | -167 | -1,169 | -1,837 | -12,859 | -25,453 | -178,171 | -279,983 | -1,959,881 | -4,250,651 | -29,754,557 | -46,757,161 | -327,300,127 |
