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 27,600,515, 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 | 27,600,515 | |
| -1 | -27,600,515 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 27,600,515.
Example:
1 x 27,600,515 = 27,600,515
and
-1 x -27,600,515 = 27,600,515
Notice both answers equal 27,600,515
With that explanation out of the way, let's continue. Next, we take the number 27,600,515 and divide it by 2:
27,600,515 ÷ 2 = 13,800,257.5
If the quotient is a whole number, then 2 and 13,800,257.5 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 | 27,600,515 | |
| -1 | -27,600,515 |
Now, we try dividing 27,600,515 by 3:
27,600,515 ÷ 3 = 9,200,171.6667
If the quotient is a whole number, then 3 and 9,200,171.6667 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 | 27,600,515 | |
| -1 | -27,600,515 |
Let's try dividing by 4:
27,600,515 ÷ 4 = 6,900,128.75
If the quotient is a whole number, then 4 and 6,900,128.75 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 | 27,600,515 | |
| -1 | 27,600,515 |
If you did it right, you will end up with this table:
| 1 | 5 | 47 | 235 | 257 | 457 | 1,285 | 2,285 | 12,079 | 21,479 | 60,395 | 107,395 | 117,449 | 587,245 | 5,520,103 | 27,600,515 |
| -1 | -5 | -47 | -235 | -257 | -457 | -1,285 | -2,285 | -12,079 | -21,479 | -60,395 | -107,395 | -117,449 | -587,245 | -5,520,103 | -27,600,515 |
