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 6,788,023, 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 | 6,788,023 | |
| -1 | -6,788,023 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 6,788,023.
Example:
1 x 6,788,023 = 6,788,023
and
-1 x -6,788,023 = 6,788,023
Notice both answers equal 6,788,023
With that explanation out of the way, let's continue. Next, we take the number 6,788,023 and divide it by 2:
6,788,023 ÷ 2 = 3,394,011.5
If the quotient is a whole number, then 2 and 3,394,011.5 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 | 6,788,023 | |
| -1 | -6,788,023 |
Now, we try dividing 6,788,023 by 3:
6,788,023 ÷ 3 = 2,262,674.3333
If the quotient is a whole number, then 3 and 2,262,674.3333 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 | 6,788,023 | |
| -1 | -6,788,023 |
Let's try dividing by 4:
6,788,023 ÷ 4 = 1,697,005.75
If the quotient is a whole number, then 4 and 1,697,005.75 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 | 6,788,023 | |
| -1 | 6,788,023 |
If you did it right, you will end up with this table:
| 1 | 11 | 43 | 113 | 127 | 473 | 1,243 | 1,397 | 4,859 | 5,461 | 14,351 | 53,449 | 60,071 | 157,861 | 617,093 | 6,788,023 |
| -1 | -11 | -43 | -113 | -127 | -473 | -1,243 | -1,397 | -4,859 | -5,461 | -14,351 | -53,449 | -60,071 | -157,861 | -617,093 | -6,788,023 |
