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 12,730,835, 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 | 12,730,835 | |
| -1 | -12,730,835 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,730,835.
Example:
1 x 12,730,835 = 12,730,835
and
-1 x -12,730,835 = 12,730,835
Notice both answers equal 12,730,835
With that explanation out of the way, let's continue. Next, we take the number 12,730,835 and divide it by 2:
12,730,835 ÷ 2 = 6,365,417.5
If the quotient is a whole number, then 2 and 6,365,417.5 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 | 12,730,835 | |
| -1 | -12,730,835 |
Now, we try dividing 12,730,835 by 3:
12,730,835 ÷ 3 = 4,243,611.6667
If the quotient is a whole number, then 3 and 4,243,611.6667 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 | 12,730,835 | |
| -1 | -12,730,835 |
Let's try dividing by 4:
12,730,835 ÷ 4 = 3,182,708.75
If the quotient is a whole number, then 4 and 3,182,708.75 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 | 12,730,835 | |
| -1 | 12,730,835 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 73 | 365 | 949 | 2,683 | 4,745 | 13,415 | 34,879 | 174,395 | 195,859 | 979,295 | 2,546,167 | 12,730,835 |
| -1 | -5 | -13 | -65 | -73 | -365 | -949 | -2,683 | -4,745 | -13,415 | -34,879 | -174,395 | -195,859 | -979,295 | -2,546,167 | -12,730,835 |
