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 7,796,375, 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 | 7,796,375 | |
| -1 | -7,796,375 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,796,375.
Example:
1 x 7,796,375 = 7,796,375
and
-1 x -7,796,375 = 7,796,375
Notice both answers equal 7,796,375
With that explanation out of the way, let's continue. Next, we take the number 7,796,375 and divide it by 2:
7,796,375 ÷ 2 = 3,898,187.5
If the quotient is a whole number, then 2 and 3,898,187.5 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 | 7,796,375 | |
| -1 | -7,796,375 |
Now, we try dividing 7,796,375 by 3:
7,796,375 ÷ 3 = 2,598,791.6667
If the quotient is a whole number, then 3 and 2,598,791.6667 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 | 7,796,375 | |
| -1 | -7,796,375 |
Let's try dividing by 4:
7,796,375 ÷ 4 = 1,949,093.75
If the quotient is a whole number, then 4 and 1,949,093.75 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 | 7,796,375 | |
| -1 | 7,796,375 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 97 | 125 | 485 | 643 | 2,425 | 3,215 | 12,125 | 16,075 | 62,371 | 80,375 | 311,855 | 1,559,275 | 7,796,375 |
| -1 | -5 | -25 | -97 | -125 | -485 | -643 | -2,425 | -3,215 | -12,125 | -16,075 | -62,371 | -80,375 | -311,855 | -1,559,275 | -7,796,375 |
