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 27,225,275, 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 | 27,225,275 | |
| -1 | -27,225,275 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 27,225,275.
Example:
1 x 27,225,275 = 27,225,275
and
-1 x -27,225,275 = 27,225,275
Notice both answers equal 27,225,275
With that explanation out of the way, let's continue. Next, we take the number 27,225,275 and divide it by 2:
27,225,275 ÷ 2 = 13,612,637.5
If the quotient is a whole number, then 2 and 13,612,637.5 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 | 27,225,275 | |
| -1 | -27,225,275 |
Now, we try dividing 27,225,275 by 3:
27,225,275 ÷ 3 = 9,075,091.6667
If the quotient is a whole number, then 3 and 9,075,091.6667 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 | 27,225,275 | |
| -1 | -27,225,275 |
Let's try dividing by 4:
27,225,275 ÷ 4 = 6,806,318.75
If the quotient is a whole number, then 4 and 6,806,318.75 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 | 27,225,275 | |
| -1 | 27,225,275 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 11 | 25 | 35 | 55 | 77 | 175 | 275 | 385 | 1,925 | 14,143 | 70,715 | 99,001 | 155,573 | 353,575 | 495,005 | 777,865 | 1,089,011 | 2,475,025 | 3,889,325 | 5,445,055 | 27,225,275 |
| -1 | -5 | -7 | -11 | -25 | -35 | -55 | -77 | -175 | -275 | -385 | -1,925 | -14,143 | -70,715 | -99,001 | -155,573 | -353,575 | -495,005 | -777,865 | -1,089,011 | -2,475,025 | -3,889,325 | -5,445,055 | -27,225,275 |
