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 27,600,365, 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 | 27,600,365 | |
| -1 | -27,600,365 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 27,600,365.
Example:
1 x 27,600,365 = 27,600,365
and
-1 x -27,600,365 = 27,600,365
Notice both answers equal 27,600,365
With that explanation out of the way, let's continue. Next, we take the number 27,600,365 and divide it by 2:
27,600,365 ÷ 2 = 13,800,182.5
If the quotient is a whole number, then 2 and 13,800,182.5 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 | 27,600,365 | |
| -1 | -27,600,365 |
Now, we try dividing 27,600,365 by 3:
27,600,365 ÷ 3 = 9,200,121.6667
If the quotient is a whole number, then 3 and 9,200,121.6667 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 | 27,600,365 | |
| -1 | -27,600,365 |
Let's try dividing by 4:
27,600,365 ÷ 4 = 6,900,091.25
If the quotient is a whole number, then 4 and 6,900,091.25 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 | 27,600,365 | |
| -1 | 27,600,365 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 61 | 65 | 305 | 793 | 3,965 | 6,961 | 34,805 | 90,493 | 424,621 | 452,465 | 2,123,105 | 5,520,073 | 27,600,365 |
| -1 | -5 | -13 | -61 | -65 | -305 | -793 | -3,965 | -6,961 | -34,805 | -90,493 | -424,621 | -452,465 | -2,123,105 | -5,520,073 | -27,600,365 |
