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 27,242,735, 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 | 27,242,735 | |
| -1 | -27,242,735 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 27,242,735.
Example:
1 x 27,242,735 = 27,242,735
and
-1 x -27,242,735 = 27,242,735
Notice both answers equal 27,242,735
With that explanation out of the way, let's continue. Next, we take the number 27,242,735 and divide it by 2:
27,242,735 ÷ 2 = 13,621,367.5
If the quotient is a whole number, then 2 and 13,621,367.5 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 | 27,242,735 | |
| -1 | -27,242,735 |
Now, we try dividing 27,242,735 by 3:
27,242,735 ÷ 3 = 9,080,911.6667
If the quotient is a whole number, then 3 and 9,080,911.6667 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 | 27,242,735 | |
| -1 | -27,242,735 |
Let's try dividing by 4:
27,242,735 ÷ 4 = 6,810,683.75
If the quotient is a whole number, then 4 and 6,810,683.75 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 | 27,242,735 | |
| -1 | 27,242,735 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 107 | 535 | 1,391 | 3,917 | 6,955 | 19,585 | 50,921 | 254,605 | 419,119 | 2,095,595 | 5,448,547 | 27,242,735 |
| -1 | -5 | -13 | -65 | -107 | -535 | -1,391 | -3,917 | -6,955 | -19,585 | -50,921 | -254,605 | -419,119 | -2,095,595 | -5,448,547 | -27,242,735 |
