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 13,204,885, 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 | 13,204,885 | |
| -1 | -13,204,885 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,204,885.
Example:
1 x 13,204,885 = 13,204,885
and
-1 x -13,204,885 = 13,204,885
Notice both answers equal 13,204,885
With that explanation out of the way, let's continue. Next, we take the number 13,204,885 and divide it by 2:
13,204,885 ÷ 2 = 6,602,442.5
If the quotient is a whole number, then 2 and 6,602,442.5 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 | 13,204,885 | |
| -1 | -13,204,885 |
Now, we try dividing 13,204,885 by 3:
13,204,885 ÷ 3 = 4,401,628.3333
If the quotient is a whole number, then 3 and 4,401,628.3333 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 | 13,204,885 | |
| -1 | -13,204,885 |
Let's try dividing by 4:
13,204,885 ÷ 4 = 3,301,221.25
If the quotient is a whole number, then 4 and 3,301,221.25 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 | 13,204,885 | |
| -1 | 13,204,885 |
If you did it right, you will end up with this table:
| 1 | 5 | 47 | 83 | 235 | 415 | 677 | 3,385 | 3,901 | 19,505 | 31,819 | 56,191 | 159,095 | 280,955 | 2,640,977 | 13,204,885 |
| -1 | -5 | -47 | -83 | -235 | -415 | -677 | -3,385 | -3,901 | -19,505 | -31,819 | -56,191 | -159,095 | -280,955 | -2,640,977 | -13,204,885 |
