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 12,024,245, 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 | 12,024,245 | |
| -1 | -12,024,245 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,024,245.
Example:
1 x 12,024,245 = 12,024,245
and
-1 x -12,024,245 = 12,024,245
Notice both answers equal 12,024,245
With that explanation out of the way, let's continue. Next, we take the number 12,024,245 and divide it by 2:
12,024,245 ÷ 2 = 6,012,122.5
If the quotient is a whole number, then 2 and 6,012,122.5 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 | 12,024,245 | |
| -1 | -12,024,245 |
Now, we try dividing 12,024,245 by 3:
12,024,245 ÷ 3 = 4,008,081.6667
If the quotient is a whole number, then 3 and 4,008,081.6667 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 | 12,024,245 | |
| -1 | -12,024,245 |
Let's try dividing by 4:
12,024,245 ÷ 4 = 3,006,061.25
If the quotient is a whole number, then 4 and 3,006,061.25 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 | 12,024,245 | |
| -1 | 12,024,245 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 47 | 95 | 235 | 893 | 2,693 | 4,465 | 13,465 | 51,167 | 126,571 | 255,835 | 632,855 | 2,404,849 | 12,024,245 |
| -1 | -5 | -19 | -47 | -95 | -235 | -893 | -2,693 | -4,465 | -13,465 | -51,167 | -126,571 | -255,835 | -632,855 | -2,404,849 | -12,024,245 |
