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 27,122,735, 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 | 27,122,735 | |
| -1 | -27,122,735 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 27,122,735.
Example:
1 x 27,122,735 = 27,122,735
and
-1 x -27,122,735 = 27,122,735
Notice both answers equal 27,122,735
With that explanation out of the way, let's continue. Next, we take the number 27,122,735 and divide it by 2:
27,122,735 ÷ 2 = 13,561,367.5
If the quotient is a whole number, then 2 and 13,561,367.5 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 | 27,122,735 | |
| -1 | -27,122,735 |
Now, we try dividing 27,122,735 by 3:
27,122,735 ÷ 3 = 9,040,911.6667
If the quotient is a whole number, then 3 and 9,040,911.6667 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 | 27,122,735 | |
| -1 | -27,122,735 |
Let's try dividing by 4:
27,122,735 ÷ 4 = 6,780,683.75
If the quotient is a whole number, then 4 and 6,780,683.75 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 | 27,122,735 | |
| -1 | 27,122,735 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 61 | 85 | 305 | 1,037 | 5,185 | 5,231 | 26,155 | 88,927 | 319,091 | 444,635 | 1,595,455 | 5,424,547 | 27,122,735 |
| -1 | -5 | -17 | -61 | -85 | -305 | -1,037 | -5,185 | -5,231 | -26,155 | -88,927 | -319,091 | -444,635 | -1,595,455 | -5,424,547 | -27,122,735 |
