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 27,013,345, 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 | 27,013,345 | |
| -1 | -27,013,345 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 27,013,345.
Example:
1 x 27,013,345 = 27,013,345
and
-1 x -27,013,345 = 27,013,345
Notice both answers equal 27,013,345
With that explanation out of the way, let's continue. Next, we take the number 27,013,345 and divide it by 2:
27,013,345 ÷ 2 = 13,506,672.5
If the quotient is a whole number, then 2 and 13,506,672.5 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 | 27,013,345 | |
| -1 | -27,013,345 |
Now, we try dividing 27,013,345 by 3:
27,013,345 ÷ 3 = 9,004,448.3333
If the quotient is a whole number, then 3 and 9,004,448.3333 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 | 27,013,345 | |
| -1 | -27,013,345 |
Let's try dividing by 4:
27,013,345 ÷ 4 = 6,753,336.25
If the quotient is a whole number, then 4 and 6,753,336.25 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 | 27,013,345 | |
| -1 | 27,013,345 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 95 | 181 | 905 | 1,571 | 3,439 | 7,855 | 17,195 | 29,849 | 149,245 | 284,351 | 1,421,755 | 5,402,669 | 27,013,345 |
| -1 | -5 | -19 | -95 | -181 | -905 | -1,571 | -3,439 | -7,855 | -17,195 | -29,849 | -149,245 | -284,351 | -1,421,755 | -5,402,669 | -27,013,345 |
