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 8,388,653, 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 | 8,388,653 | |
| -1 | -8,388,653 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,388,653.
Example:
1 x 8,388,653 = 8,388,653
and
-1 x -8,388,653 = 8,388,653
Notice both answers equal 8,388,653
With that explanation out of the way, let's continue. Next, we take the number 8,388,653 and divide it by 2:
8,388,653 ÷ 2 = 4,194,326.5
If the quotient is a whole number, then 2 and 4,194,326.5 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 | 8,388,653 | |
| -1 | -8,388,653 |
Now, we try dividing 8,388,653 by 3:
8,388,653 ÷ 3 = 2,796,217.6667
If the quotient is a whole number, then 3 and 2,796,217.6667 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 | 8,388,653 | |
| -1 | -8,388,653 |
Let's try dividing by 4:
8,388,653 ÷ 4 = 2,097,163.25
If the quotient is a whole number, then 4 and 2,097,163.25 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 | 8,388,653 | |
| -1 | 8,388,653 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 49 | 91 | 169 | 637 | 1,013 | 1,183 | 7,091 | 8,281 | 13,169 | 49,637 | 92,183 | 171,197 | 645,281 | 1,198,379 | 8,388,653 |
| -1 | -7 | -13 | -49 | -91 | -169 | -637 | -1,013 | -1,183 | -7,091 | -8,281 | -13,169 | -49,637 | -92,183 | -171,197 | -645,281 | -1,198,379 | -8,388,653 |
