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 12,088,405, 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 | 12,088,405 | |
| -1 | -12,088,405 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,088,405.
Example:
1 x 12,088,405 = 12,088,405
and
-1 x -12,088,405 = 12,088,405
Notice both answers equal 12,088,405
With that explanation out of the way, let's continue. Next, we take the number 12,088,405 and divide it by 2:
12,088,405 ÷ 2 = 6,044,202.5
If the quotient is a whole number, then 2 and 6,044,202.5 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 | 12,088,405 | |
| -1 | -12,088,405 |
Now, we try dividing 12,088,405 by 3:
12,088,405 ÷ 3 = 4,029,468.3333
If the quotient is a whole number, then 3 and 4,029,468.3333 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 | 12,088,405 | |
| -1 | -12,088,405 |
Let's try dividing by 4:
12,088,405 ÷ 4 = 3,022,101.25
If the quotient is a whole number, then 4 and 3,022,101.25 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 | 12,088,405 | |
| -1 | 12,088,405 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 569 | 607 | 2,845 | 3,035 | 3,983 | 4,249 | 19,915 | 21,245 | 345,383 | 1,726,915 | 2,417,681 | 12,088,405 |
| -1 | -5 | -7 | -35 | -569 | -607 | -2,845 | -3,035 | -3,983 | -4,249 | -19,915 | -21,245 | -345,383 | -1,726,915 | -2,417,681 | -12,088,405 |
