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 12,365,005, 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 | 12,365,005 | |
| -1 | -12,365,005 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,365,005.
Example:
1 x 12,365,005 = 12,365,005
and
-1 x -12,365,005 = 12,365,005
Notice both answers equal 12,365,005
With that explanation out of the way, let's continue. Next, we take the number 12,365,005 and divide it by 2:
12,365,005 ÷ 2 = 6,182,502.5
If the quotient is a whole number, then 2 and 6,182,502.5 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 | 12,365,005 | |
| -1 | -12,365,005 |
Now, we try dividing 12,365,005 by 3:
12,365,005 ÷ 3 = 4,121,668.3333
If the quotient is a whole number, then 3 and 4,121,668.3333 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 | 12,365,005 | |
| -1 | -12,365,005 |
Let's try dividing by 4:
12,365,005 ÷ 4 = 3,091,251.25
If the quotient is a whole number, then 4 and 3,091,251.25 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 | 12,365,005 | |
| -1 | 12,365,005 |
If you did it right, you will end up with this table:
| 1 | 5 | 61 | 71 | 305 | 355 | 571 | 2,855 | 4,331 | 21,655 | 34,831 | 40,541 | 174,155 | 202,705 | 2,473,001 | 12,365,005 |
| -1 | -5 | -61 | -71 | -305 | -355 | -571 | -2,855 | -4,331 | -21,655 | -34,831 | -40,541 | -174,155 | -202,705 | -2,473,001 | -12,365,005 |
