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 27,051,395, 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 | 27,051,395 | |
| -1 | -27,051,395 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 27,051,395.
Example:
1 x 27,051,395 = 27,051,395
and
-1 x -27,051,395 = 27,051,395
Notice both answers equal 27,051,395
With that explanation out of the way, let's continue. Next, we take the number 27,051,395 and divide it by 2:
27,051,395 ÷ 2 = 13,525,697.5
If the quotient is a whole number, then 2 and 13,525,697.5 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 | 27,051,395 | |
| -1 | -27,051,395 |
Now, we try dividing 27,051,395 by 3:
27,051,395 ÷ 3 = 9,017,131.6667
If the quotient is a whole number, then 3 and 9,017,131.6667 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 | 27,051,395 | |
| -1 | -27,051,395 |
Let's try dividing by 4:
27,051,395 ÷ 4 = 6,762,848.75
If the quotient is a whole number, then 4 and 6,762,848.75 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 | 27,051,395 | |
| -1 | 27,051,395 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 757 | 1,021 | 3,785 | 5,105 | 5,299 | 7,147 | 26,495 | 35,735 | 772,897 | 3,864,485 | 5,410,279 | 27,051,395 |
| -1 | -5 | -7 | -35 | -757 | -1,021 | -3,785 | -5,105 | -5,299 | -7,147 | -26,495 | -35,735 | -772,897 | -3,864,485 | -5,410,279 | -27,051,395 |
