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 13,323,505, 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 | 13,323,505 | |
| -1 | -13,323,505 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,323,505.
Example:
1 x 13,323,505 = 13,323,505
and
-1 x -13,323,505 = 13,323,505
Notice both answers equal 13,323,505
With that explanation out of the way, let's continue. Next, we take the number 13,323,505 and divide it by 2:
13,323,505 ÷ 2 = 6,661,752.5
If the quotient is a whole number, then 2 and 6,661,752.5 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 | 13,323,505 | |
| -1 | -13,323,505 |
Now, we try dividing 13,323,505 by 3:
13,323,505 ÷ 3 = 4,441,168.3333
If the quotient is a whole number, then 3 and 4,441,168.3333 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 | 13,323,505 | |
| -1 | -13,323,505 |
Let's try dividing by 4:
13,323,505 ÷ 4 = 3,330,876.25
If the quotient is a whole number, then 4 and 3,330,876.25 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 | 13,323,505 | |
| -1 | 13,323,505 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 71 | 355 | 923 | 2,887 | 4,615 | 14,435 | 37,531 | 187,655 | 204,977 | 1,024,885 | 2,664,701 | 13,323,505 |
| -1 | -5 | -13 | -65 | -71 | -355 | -923 | -2,887 | -4,615 | -14,435 | -37,531 | -187,655 | -204,977 | -1,024,885 | -2,664,701 | -13,323,505 |
