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 10,839,625, 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 | 10,839,625 | |
| -1 | -10,839,625 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,839,625.
Example:
1 x 10,839,625 = 10,839,625
and
-1 x -10,839,625 = 10,839,625
Notice both answers equal 10,839,625
With that explanation out of the way, let's continue. Next, we take the number 10,839,625 and divide it by 2:
10,839,625 ÷ 2 = 5,419,812.5
If the quotient is a whole number, then 2 and 5,419,812.5 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 | 10,839,625 | |
| -1 | -10,839,625 |
Now, we try dividing 10,839,625 by 3:
10,839,625 ÷ 3 = 3,613,208.3333
If the quotient is a whole number, then 3 and 3,613,208.3333 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 | 10,839,625 | |
| -1 | -10,839,625 |
Let's try dividing by 4:
10,839,625 ÷ 4 = 2,709,906.25
If the quotient is a whole number, then 4 and 2,709,906.25 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 | 10,839,625 | |
| -1 | 10,839,625 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 25 | 85 | 125 | 425 | 2,125 | 5,101 | 25,505 | 86,717 | 127,525 | 433,585 | 637,625 | 2,167,925 | 10,839,625 |
| -1 | -5 | -17 | -25 | -85 | -125 | -425 | -2,125 | -5,101 | -25,505 | -86,717 | -127,525 | -433,585 | -637,625 | -2,167,925 | -10,839,625 |
