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 27,239,875, 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 | 27,239,875 | |
| -1 | -27,239,875 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 27,239,875.
Example:
1 x 27,239,875 = 27,239,875
and
-1 x -27,239,875 = 27,239,875
Notice both answers equal 27,239,875
With that explanation out of the way, let's continue. Next, we take the number 27,239,875 and divide it by 2:
27,239,875 ÷ 2 = 13,619,937.5
If the quotient is a whole number, then 2 and 13,619,937.5 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 | 27,239,875 | |
| -1 | -27,239,875 |
Now, we try dividing 27,239,875 by 3:
27,239,875 ÷ 3 = 9,079,958.3333
If the quotient is a whole number, then 3 and 9,079,958.3333 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 | 27,239,875 | |
| -1 | -27,239,875 |
Let's try dividing by 4:
27,239,875 ÷ 4 = 6,809,968.75
If the quotient is a whole number, then 4 and 6,809,968.75 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 | 27,239,875 | |
| -1 | 27,239,875 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 25 | 65 | 125 | 325 | 1,625 | 16,763 | 83,815 | 217,919 | 419,075 | 1,089,595 | 2,095,375 | 5,447,975 | 27,239,875 |
| -1 | -5 | -13 | -25 | -65 | -125 | -325 | -1,625 | -16,763 | -83,815 | -217,919 | -419,075 | -1,089,595 | -2,095,375 | -5,447,975 | -27,239,875 |
