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 27,009,275, 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 | 27,009,275 | |
| -1 | -27,009,275 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 27,009,275.
Example:
1 x 27,009,275 = 27,009,275
and
-1 x -27,009,275 = 27,009,275
Notice both answers equal 27,009,275
With that explanation out of the way, let's continue. Next, we take the number 27,009,275 and divide it by 2:
27,009,275 ÷ 2 = 13,504,637.5
If the quotient is a whole number, then 2 and 13,504,637.5 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 | 27,009,275 | |
| -1 | -27,009,275 |
Now, we try dividing 27,009,275 by 3:
27,009,275 ÷ 3 = 9,003,091.6667
If the quotient is a whole number, then 3 and 9,003,091.6667 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 | 27,009,275 | |
| -1 | -27,009,275 |
Let's try dividing by 4:
27,009,275 ÷ 4 = 6,752,318.75
If the quotient is a whole number, then 4 and 6,752,318.75 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 | 27,009,275 | |
| -1 | 27,009,275 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 61 | 89 | 199 | 305 | 445 | 995 | 1,525 | 2,225 | 4,975 | 5,429 | 12,139 | 17,711 | 27,145 | 60,695 | 88,555 | 135,725 | 303,475 | 442,775 | 1,080,371 | 5,401,855 | 27,009,275 |
| -1 | -5 | -25 | -61 | -89 | -199 | -305 | -445 | -995 | -1,525 | -2,225 | -4,975 | -5,429 | -12,139 | -17,711 | -27,145 | -60,695 | -88,555 | -135,725 | -303,475 | -442,775 | -1,080,371 | -5,401,855 | -27,009,275 |
