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 7,904,659, 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 | 7,904,659 | |
| -1 | -7,904,659 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,904,659.
Example:
1 x 7,904,659 = 7,904,659
and
-1 x -7,904,659 = 7,904,659
Notice both answers equal 7,904,659
With that explanation out of the way, let's continue. Next, we take the number 7,904,659 and divide it by 2:
7,904,659 ÷ 2 = 3,952,329.5
If the quotient is a whole number, then 2 and 3,952,329.5 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 | 7,904,659 | |
| -1 | -7,904,659 |
Now, we try dividing 7,904,659 by 3:
7,904,659 ÷ 3 = 2,634,886.3333
If the quotient is a whole number, then 3 and 2,634,886.3333 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 | 7,904,659 | |
| -1 | -7,904,659 |
Let's try dividing by 4:
7,904,659 ÷ 4 = 1,976,164.75
If the quotient is a whole number, then 4 and 1,976,164.75 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 | 7,904,659 | |
| -1 | 7,904,659 |
If you did it right, you will end up with this table:
| 1 | 7 | 31 | 73 | 217 | 499 | 511 | 2,263 | 3,493 | 15,469 | 15,841 | 36,427 | 108,283 | 254,989 | 1,129,237 | 7,904,659 |
| -1 | -7 | -31 | -73 | -217 | -499 | -511 | -2,263 | -3,493 | -15,469 | -15,841 | -36,427 | -108,283 | -254,989 | -1,129,237 | -7,904,659 |
