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 27,601,115, 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 | 27,601,115 | |
| -1 | -27,601,115 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 27,601,115.
Example:
1 x 27,601,115 = 27,601,115
and
-1 x -27,601,115 = 27,601,115
Notice both answers equal 27,601,115
With that explanation out of the way, let's continue. Next, we take the number 27,601,115 and divide it by 2:
27,601,115 ÷ 2 = 13,800,557.5
If the quotient is a whole number, then 2 and 13,800,557.5 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 | 27,601,115 | |
| -1 | -27,601,115 |
Now, we try dividing 27,601,115 by 3:
27,601,115 ÷ 3 = 9,200,371.6667
If the quotient is a whole number, then 3 and 9,200,371.6667 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 | 27,601,115 | |
| -1 | -27,601,115 |
Let's try dividing by 4:
27,601,115 ÷ 4 = 6,900,278.75
If the quotient is a whole number, then 4 and 6,900,278.75 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 | 27,601,115 | |
| -1 | 27,601,115 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 443 | 733 | 2,215 | 3,665 | 7,531 | 12,461 | 37,655 | 62,305 | 324,719 | 1,623,595 | 5,520,223 | 27,601,115 |
| -1 | -5 | -17 | -85 | -443 | -733 | -2,215 | -3,665 | -7,531 | -12,461 | -37,655 | -62,305 | -324,719 | -1,623,595 | -5,520,223 | -27,601,115 |
