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 27,153,365, 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 | 27,153,365 | |
| -1 | -27,153,365 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 27,153,365.
Example:
1 x 27,153,365 = 27,153,365
and
-1 x -27,153,365 = 27,153,365
Notice both answers equal 27,153,365
With that explanation out of the way, let's continue. Next, we take the number 27,153,365 and divide it by 2:
27,153,365 ÷ 2 = 13,576,682.5
If the quotient is a whole number, then 2 and 13,576,682.5 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 | 27,153,365 | |
| -1 | -27,153,365 |
Now, we try dividing 27,153,365 by 3:
27,153,365 ÷ 3 = 9,051,121.6667
If the quotient is a whole number, then 3 and 9,051,121.6667 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 | 27,153,365 | |
| -1 | -27,153,365 |
Let's try dividing by 4:
27,153,365 ÷ 4 = 6,788,341.25
If the quotient is a whole number, then 4 and 6,788,341.25 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 | 27,153,365 | |
| -1 | 27,153,365 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 155 | 167 | 835 | 1,049 | 5,177 | 5,245 | 25,885 | 32,519 | 162,595 | 175,183 | 875,915 | 5,430,673 | 27,153,365 |
| -1 | -5 | -31 | -155 | -167 | -835 | -1,049 | -5,177 | -5,245 | -25,885 | -32,519 | -162,595 | -175,183 | -875,915 | -5,430,673 | -27,153,365 |
