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 27,235,607, 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 | 27,235,607 | |
| -1 | -27,235,607 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 27,235,607.
Example:
1 x 27,235,607 = 27,235,607
and
-1 x -27,235,607 = 27,235,607
Notice both answers equal 27,235,607
With that explanation out of the way, let's continue. Next, we take the number 27,235,607 and divide it by 2:
27,235,607 ÷ 2 = 13,617,803.5
If the quotient is a whole number, then 2 and 13,617,803.5 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 | 27,235,607 | |
| -1 | -27,235,607 |
Now, we try dividing 27,235,607 by 3:
27,235,607 ÷ 3 = 9,078,535.6667
If the quotient is a whole number, then 3 and 9,078,535.6667 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 | 27,235,607 | |
| -1 | -27,235,607 |
Let's try dividing by 4:
27,235,607 ÷ 4 = 6,808,901.75
If the quotient is a whole number, then 4 and 6,808,901.75 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 | 27,235,607 | |
| -1 | 27,235,607 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 47 | 133 | 329 | 893 | 4,357 | 6,251 | 30,499 | 82,783 | 204,779 | 579,481 | 1,433,453 | 3,890,801 | 27,235,607 |
| -1 | -7 | -19 | -47 | -133 | -329 | -893 | -4,357 | -6,251 | -30,499 | -82,783 | -204,779 | -579,481 | -1,433,453 | -3,890,801 | -27,235,607 |
