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 12,320,563, 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 | 12,320,563 | |
| -1 | -12,320,563 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,320,563.
Example:
1 x 12,320,563 = 12,320,563
and
-1 x -12,320,563 = 12,320,563
Notice both answers equal 12,320,563
With that explanation out of the way, let's continue. Next, we take the number 12,320,563 and divide it by 2:
12,320,563 ÷ 2 = 6,160,281.5
If the quotient is a whole number, then 2 and 6,160,281.5 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 | 12,320,563 | |
| -1 | -12,320,563 |
Now, we try dividing 12,320,563 by 3:
12,320,563 ÷ 3 = 4,106,854.3333
If the quotient is a whole number, then 3 and 4,106,854.3333 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 | 12,320,563 | |
| -1 | -12,320,563 |
Let's try dividing by 4:
12,320,563 ÷ 4 = 3,080,140.75
If the quotient is a whole number, then 4 and 3,080,140.75 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 | 12,320,563 | |
| -1 | 12,320,563 |
If you did it right, you will end up with this table:
| 1 | 17 | 29 | 67 | 373 | 493 | 1,139 | 1,943 | 6,341 | 10,817 | 24,991 | 33,031 | 183,889 | 424,847 | 724,739 | 12,320,563 |
| -1 | -17 | -29 | -67 | -373 | -493 | -1,139 | -1,943 | -6,341 | -10,817 | -24,991 | -33,031 | -183,889 | -424,847 | -724,739 | -12,320,563 |
