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 7,976,827, 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 | 7,976,827 | |
| -1 | -7,976,827 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,976,827.
Example:
1 x 7,976,827 = 7,976,827
and
-1 x -7,976,827 = 7,976,827
Notice both answers equal 7,976,827
With that explanation out of the way, let's continue. Next, we take the number 7,976,827 and divide it by 2:
7,976,827 ÷ 2 = 3,988,413.5
If the quotient is a whole number, then 2 and 3,988,413.5 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 | 7,976,827 | |
| -1 | -7,976,827 |
Now, we try dividing 7,976,827 by 3:
7,976,827 ÷ 3 = 2,658,942.3333
If the quotient is a whole number, then 3 and 2,658,942.3333 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 | 7,976,827 | |
| -1 | -7,976,827 |
Let's try dividing by 4:
7,976,827 ÷ 4 = 1,994,206.75
If the quotient is a whole number, then 4 and 1,994,206.75 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 | 7,976,827 | |
| -1 | 7,976,827 |
If you did it right, you will end up with this table:
| 1 | 19 | 29 | 31 | 467 | 551 | 589 | 899 | 8,873 | 13,543 | 14,477 | 17,081 | 257,317 | 275,063 | 419,833 | 7,976,827 |
| -1 | -19 | -29 | -31 | -467 | -551 | -589 | -899 | -8,873 | -13,543 | -14,477 | -17,081 | -257,317 | -275,063 | -419,833 | -7,976,827 |
