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 27,225,875, 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 | 27,225,875 | |
| -1 | -27,225,875 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 27,225,875.
Example:
1 x 27,225,875 = 27,225,875
and
-1 x -27,225,875 = 27,225,875
Notice both answers equal 27,225,875
With that explanation out of the way, let's continue. Next, we take the number 27,225,875 and divide it by 2:
27,225,875 ÷ 2 = 13,612,937.5
If the quotient is a whole number, then 2 and 13,612,937.5 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 | 27,225,875 | |
| -1 | -27,225,875 |
Now, we try dividing 27,225,875 by 3:
27,225,875 ÷ 3 = 9,075,291.6667
If the quotient is a whole number, then 3 and 9,075,291.6667 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 | 27,225,875 | |
| -1 | -27,225,875 |
Let's try dividing by 4:
27,225,875 ÷ 4 = 6,806,468.75
If the quotient is a whole number, then 4 and 6,806,468.75 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 | 27,225,875 | |
| -1 | 27,225,875 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 125 | 173 | 865 | 1,259 | 4,325 | 6,295 | 21,625 | 31,475 | 157,375 | 217,807 | 1,089,035 | 5,445,175 | 27,225,875 |
| -1 | -5 | -25 | -125 | -173 | -865 | -1,259 | -4,325 | -6,295 | -21,625 | -31,475 | -157,375 | -217,807 | -1,089,035 | -5,445,175 | -27,225,875 |
