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 13,104,623, 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 | 13,104,623 | |
| -1 | -13,104,623 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,104,623.
Example:
1 x 13,104,623 = 13,104,623
and
-1 x -13,104,623 = 13,104,623
Notice both answers equal 13,104,623
With that explanation out of the way, let's continue. Next, we take the number 13,104,623 and divide it by 2:
13,104,623 ÷ 2 = 6,552,311.5
If the quotient is a whole number, then 2 and 6,552,311.5 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 | 13,104,623 | |
| -1 | -13,104,623 |
Now, we try dividing 13,104,623 by 3:
13,104,623 ÷ 3 = 4,368,207.6667
If the quotient is a whole number, then 3 and 4,368,207.6667 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 | 13,104,623 | |
| -1 | -13,104,623 |
Let's try dividing by 4:
13,104,623 ÷ 4 = 3,276,155.75
If the quotient is a whole number, then 4 and 3,276,155.75 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 | 13,104,623 | |
| -1 | 13,104,623 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 37 | 133 | 259 | 703 | 2,663 | 4,921 | 18,641 | 50,597 | 98,531 | 354,179 | 689,717 | 1,872,089 | 13,104,623 |
| -1 | -7 | -19 | -37 | -133 | -259 | -703 | -2,663 | -4,921 | -18,641 | -50,597 | -98,531 | -354,179 | -689,717 | -1,872,089 | -13,104,623 |
