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 27,474,005, 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 | 27,474,005 | |
| -1 | -27,474,005 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 27,474,005.
Example:
1 x 27,474,005 = 27,474,005
and
-1 x -27,474,005 = 27,474,005
Notice both answers equal 27,474,005
With that explanation out of the way, let's continue. Next, we take the number 27,474,005 and divide it by 2:
27,474,005 ÷ 2 = 13,737,002.5
If the quotient is a whole number, then 2 and 13,737,002.5 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 | 27,474,005 | |
| -1 | -27,474,005 |
Now, we try dividing 27,474,005 by 3:
27,474,005 ÷ 3 = 9,158,001.6667
If the quotient is a whole number, then 3 and 9,158,001.6667 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 | 27,474,005 | |
| -1 | -27,474,005 |
Let's try dividing by 4:
27,474,005 ÷ 4 = 6,868,501.25
If the quotient is a whole number, then 4 and 6,868,501.25 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 | 27,474,005 | |
| -1 | 27,474,005 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 167 | 835 | 2,171 | 2,531 | 10,855 | 12,655 | 32,903 | 164,515 | 422,677 | 2,113,385 | 5,494,801 | 27,474,005 |
| -1 | -5 | -13 | -65 | -167 | -835 | -2,171 | -2,531 | -10,855 | -12,655 | -32,903 | -164,515 | -422,677 | -2,113,385 | -5,494,801 | -27,474,005 |
