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 13,150,709, 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 | 13,150,709 | |
| -1 | -13,150,709 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,150,709.
Example:
1 x 13,150,709 = 13,150,709
and
-1 x -13,150,709 = 13,150,709
Notice both answers equal 13,150,709
With that explanation out of the way, let's continue. Next, we take the number 13,150,709 and divide it by 2:
13,150,709 ÷ 2 = 6,575,354.5
If the quotient is a whole number, then 2 and 6,575,354.5 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 | 13,150,709 | |
| -1 | -13,150,709 |
Now, we try dividing 13,150,709 by 3:
13,150,709 ÷ 3 = 4,383,569.6667
If the quotient is a whole number, then 3 and 4,383,569.6667 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 | 13,150,709 | |
| -1 | -13,150,709 |
Let's try dividing by 4:
13,150,709 ÷ 4 = 3,287,677.25
If the quotient is a whole number, then 4 and 3,287,677.25 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 | 13,150,709 | |
| -1 | 13,150,709 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 41 | 143 | 451 | 533 | 2,243 | 5,863 | 24,673 | 29,159 | 91,963 | 320,749 | 1,011,593 | 1,195,519 | 13,150,709 |
| -1 | -11 | -13 | -41 | -143 | -451 | -533 | -2,243 | -5,863 | -24,673 | -29,159 | -91,963 | -320,749 | -1,011,593 | -1,195,519 | -13,150,709 |
