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 13,793,665, 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 | 13,793,665 | |
| -1 | -13,793,665 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,793,665.
Example:
1 x 13,793,665 = 13,793,665
and
-1 x -13,793,665 = 13,793,665
Notice both answers equal 13,793,665
With that explanation out of the way, let's continue. Next, we take the number 13,793,665 and divide it by 2:
13,793,665 ÷ 2 = 6,896,832.5
If the quotient is a whole number, then 2 and 6,896,832.5 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 | 13,793,665 | |
| -1 | -13,793,665 |
Now, we try dividing 13,793,665 by 3:
13,793,665 ÷ 3 = 4,597,888.3333
If the quotient is a whole number, then 3 and 4,597,888.3333 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 | 13,793,665 | |
| -1 | -13,793,665 |
Let's try dividing by 4:
13,793,665 ÷ 4 = 3,448,416.25
If the quotient is a whole number, then 4 and 3,448,416.25 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 | 13,793,665 | |
| -1 | 13,793,665 |
If you did it right, you will end up with this table:
| 1 | 5 | 89 | 139 | 223 | 445 | 695 | 1,115 | 12,371 | 19,847 | 30,997 | 61,855 | 99,235 | 154,985 | 2,758,733 | 13,793,665 |
| -1 | -5 | -89 | -139 | -223 | -445 | -695 | -1,115 | -12,371 | -19,847 | -30,997 | -61,855 | -99,235 | -154,985 | -2,758,733 | -13,793,665 |
