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 12,049,355, 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 | 12,049,355 | |
| -1 | -12,049,355 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,049,355.
Example:
1 x 12,049,355 = 12,049,355
and
-1 x -12,049,355 = 12,049,355
Notice both answers equal 12,049,355
With that explanation out of the way, let's continue. Next, we take the number 12,049,355 and divide it by 2:
12,049,355 ÷ 2 = 6,024,677.5
If the quotient is a whole number, then 2 and 6,024,677.5 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 | 12,049,355 | |
| -1 | -12,049,355 |
Now, we try dividing 12,049,355 by 3:
12,049,355 ÷ 3 = 4,016,451.6667
If the quotient is a whole number, then 3 and 4,016,451.6667 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 | 12,049,355 | |
| -1 | -12,049,355 |
Let's try dividing by 4:
12,049,355 ÷ 4 = 3,012,338.75
If the quotient is a whole number, then 4 and 3,012,338.75 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 | 12,049,355 | |
| -1 | 12,049,355 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 29 | 115 | 145 | 667 | 3,335 | 3,613 | 18,065 | 83,099 | 104,777 | 415,495 | 523,885 | 2,409,871 | 12,049,355 |
| -1 | -5 | -23 | -29 | -115 | -145 | -667 | -3,335 | -3,613 | -18,065 | -83,099 | -104,777 | -415,495 | -523,885 | -2,409,871 | -12,049,355 |
