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 12,324,851, 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 | 12,324,851 | |
| -1 | -12,324,851 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,324,851.
Example:
1 x 12,324,851 = 12,324,851
and
-1 x -12,324,851 = 12,324,851
Notice both answers equal 12,324,851
With that explanation out of the way, let's continue. Next, we take the number 12,324,851 and divide it by 2:
12,324,851 ÷ 2 = 6,162,425.5
If the quotient is a whole number, then 2 and 6,162,425.5 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 | 12,324,851 | |
| -1 | -12,324,851 |
Now, we try dividing 12,324,851 by 3:
12,324,851 ÷ 3 = 4,108,283.6667
If the quotient is a whole number, then 3 and 4,108,283.6667 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 | 12,324,851 | |
| -1 | -12,324,851 |
Let's try dividing by 4:
12,324,851 ÷ 4 = 3,081,212.75
If the quotient is a whole number, then 4 and 3,081,212.75 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 | 12,324,851 | |
| -1 | 12,324,851 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 67 | 77 | 469 | 737 | 2,389 | 5,159 | 16,723 | 26,279 | 160,063 | 183,953 | 1,120,441 | 1,760,693 | 12,324,851 |
| -1 | -7 | -11 | -67 | -77 | -469 | -737 | -2,389 | -5,159 | -16,723 | -26,279 | -160,063 | -183,953 | -1,120,441 | -1,760,693 | -12,324,851 |
