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 27,132,665, 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 | 27,132,665 | |
| -1 | -27,132,665 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 27,132,665.
Example:
1 x 27,132,665 = 27,132,665
and
-1 x -27,132,665 = 27,132,665
Notice both answers equal 27,132,665
With that explanation out of the way, let's continue. Next, we take the number 27,132,665 and divide it by 2:
27,132,665 ÷ 2 = 13,566,332.5
If the quotient is a whole number, then 2 and 13,566,332.5 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 | 27,132,665 | |
| -1 | -27,132,665 |
Now, we try dividing 27,132,665 by 3:
27,132,665 ÷ 3 = 9,044,221.6667
If the quotient is a whole number, then 3 and 9,044,221.6667 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 | 27,132,665 | |
| -1 | -27,132,665 |
Let's try dividing by 4:
27,132,665 ÷ 4 = 6,783,166.25
If the quotient is a whole number, then 4 and 6,783,166.25 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 | 27,132,665 | |
| -1 | 27,132,665 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 19 | 35 | 95 | 133 | 665 | 40,801 | 204,005 | 285,607 | 775,219 | 1,428,035 | 3,876,095 | 5,426,533 | 27,132,665 |
| -1 | -5 | -7 | -19 | -35 | -95 | -133 | -665 | -40,801 | -204,005 | -285,607 | -775,219 | -1,428,035 | -3,876,095 | -5,426,533 | -27,132,665 |
