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 27,067,885, 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 | 27,067,885 | |
| -1 | -27,067,885 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 27,067,885.
Example:
1 x 27,067,885 = 27,067,885
and
-1 x -27,067,885 = 27,067,885
Notice both answers equal 27,067,885
With that explanation out of the way, let's continue. Next, we take the number 27,067,885 and divide it by 2:
27,067,885 ÷ 2 = 13,533,942.5
If the quotient is a whole number, then 2 and 13,533,942.5 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 | 27,067,885 | |
| -1 | -27,067,885 |
Now, we try dividing 27,067,885 by 3:
27,067,885 ÷ 3 = 9,022,628.3333
If the quotient is a whole number, then 3 and 9,022,628.3333 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 | 27,067,885 | |
| -1 | -27,067,885 |
Let's try dividing by 4:
27,067,885 ÷ 4 = 6,766,971.25
If the quotient is a whole number, then 4 and 6,766,971.25 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 | 27,067,885 | |
| -1 | 27,067,885 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 103 | 169 | 311 | 515 | 845 | 1,339 | 1,555 | 4,043 | 6,695 | 17,407 | 20,215 | 32,033 | 52,559 | 87,035 | 160,165 | 262,795 | 416,429 | 2,082,145 | 5,413,577 | 27,067,885 |
| -1 | -5 | -13 | -65 | -103 | -169 | -311 | -515 | -845 | -1,339 | -1,555 | -4,043 | -6,695 | -17,407 | -20,215 | -32,033 | -52,559 | -87,035 | -160,165 | -262,795 | -416,429 | -2,082,145 | -5,413,577 | -27,067,885 |
