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 12,013,235, 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 | 12,013,235 | |
| -1 | -12,013,235 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,013,235.
Example:
1 x 12,013,235 = 12,013,235
and
-1 x -12,013,235 = 12,013,235
Notice both answers equal 12,013,235
With that explanation out of the way, let's continue. Next, we take the number 12,013,235 and divide it by 2:
12,013,235 ÷ 2 = 6,006,617.5
If the quotient is a whole number, then 2 and 6,006,617.5 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 | 12,013,235 | |
| -1 | -12,013,235 |
Now, we try dividing 12,013,235 by 3:
12,013,235 ÷ 3 = 4,004,411.6667
If the quotient is a whole number, then 3 and 4,004,411.6667 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 | 12,013,235 | |
| -1 | -12,013,235 |
Let's try dividing by 4:
12,013,235 ÷ 4 = 3,003,308.75
If the quotient is a whole number, then 4 and 3,003,308.75 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 | 12,013,235 | |
| -1 | 12,013,235 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 421 | 439 | 2,105 | 2,195 | 5,473 | 5,707 | 27,365 | 28,535 | 184,819 | 924,095 | 2,402,647 | 12,013,235 |
| -1 | -5 | -13 | -65 | -421 | -439 | -2,105 | -2,195 | -5,473 | -5,707 | -27,365 | -28,535 | -184,819 | -924,095 | -2,402,647 | -12,013,235 |
