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 13,392,511, 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 | 13,392,511 | |
| -1 | -13,392,511 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,392,511.
Example:
1 x 13,392,511 = 13,392,511
and
-1 x -13,392,511 = 13,392,511
Notice both answers equal 13,392,511
With that explanation out of the way, let's continue. Next, we take the number 13,392,511 and divide it by 2:
13,392,511 ÷ 2 = 6,696,255.5
If the quotient is a whole number, then 2 and 6,696,255.5 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 | 13,392,511 | |
| -1 | -13,392,511 |
Now, we try dividing 13,392,511 by 3:
13,392,511 ÷ 3 = 4,464,170.3333
If the quotient is a whole number, then 3 and 4,464,170.3333 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 | 13,392,511 | |
| -1 | -13,392,511 |
Let's try dividing by 4:
13,392,511 ÷ 4 = 3,348,127.75
If the quotient is a whole number, then 4 and 3,348,127.75 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 | 13,392,511 | |
| -1 | 13,392,511 |
If you did it right, you will end up with this table:
| 1 | 11 | 19 | 139 | 209 | 461 | 1,529 | 2,641 | 5,071 | 8,759 | 29,051 | 64,079 | 96,349 | 704,869 | 1,217,501 | 13,392,511 |
| -1 | -11 | -19 | -139 | -209 | -461 | -1,529 | -2,641 | -5,071 | -8,759 | -29,051 | -64,079 | -96,349 | -704,869 | -1,217,501 | -13,392,511 |
