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 12,963,559, 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 | 12,963,559 | |
| -1 | -12,963,559 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,963,559.
Example:
1 x 12,963,559 = 12,963,559
and
-1 x -12,963,559 = 12,963,559
Notice both answers equal 12,963,559
With that explanation out of the way, let's continue. Next, we take the number 12,963,559 and divide it by 2:
12,963,559 ÷ 2 = 6,481,779.5
If the quotient is a whole number, then 2 and 6,481,779.5 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 | 12,963,559 | |
| -1 | -12,963,559 |
Now, we try dividing 12,963,559 by 3:
12,963,559 ÷ 3 = 4,321,186.3333
If the quotient is a whole number, then 3 and 4,321,186.3333 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 | 12,963,559 | |
| -1 | -12,963,559 |
Let's try dividing by 4:
12,963,559 ÷ 4 = 3,240,889.75
If the quotient is a whole number, then 4 and 3,240,889.75 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 | 12,963,559 | |
| -1 | 12,963,559 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 73 | 161 | 511 | 1,103 | 1,679 | 7,721 | 11,753 | 25,369 | 80,519 | 177,583 | 563,633 | 1,851,937 | 12,963,559 |
| -1 | -7 | -23 | -73 | -161 | -511 | -1,103 | -1,679 | -7,721 | -11,753 | -25,369 | -80,519 | -177,583 | -563,633 | -1,851,937 | -12,963,559 |
