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 9,788,219, 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 | 9,788,219 | |
| -1 | -9,788,219 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 9,788,219.
Example:
1 x 9,788,219 = 9,788,219
and
-1 x -9,788,219 = 9,788,219
Notice both answers equal 9,788,219
With that explanation out of the way, let's continue. Next, we take the number 9,788,219 and divide it by 2:
9,788,219 ÷ 2 = 4,894,109.5
If the quotient is a whole number, then 2 and 4,894,109.5 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 | 9,788,219 | |
| -1 | -9,788,219 |
Now, we try dividing 9,788,219 by 3:
9,788,219 ÷ 3 = 3,262,739.6667
If the quotient is a whole number, then 3 and 3,262,739.6667 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 | 9,788,219 | |
| -1 | -9,788,219 |
Let's try dividing by 4:
9,788,219 ÷ 4 = 2,447,054.75
If the quotient is a whole number, then 4 and 2,447,054.75 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 | 9,788,219 | |
| -1 | 9,788,219 |
If you did it right, you will end up with this table:
| 1 | 7 | 31 | 43 | 217 | 301 | 1,049 | 1,333 | 7,343 | 9,331 | 32,519 | 45,107 | 227,633 | 315,749 | 1,398,317 | 9,788,219 |
| -1 | -7 | -31 | -43 | -217 | -301 | -1,049 | -1,333 | -7,343 | -9,331 | -32,519 | -45,107 | -227,633 | -315,749 | -1,398,317 | -9,788,219 |
