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 12,011,153, 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 | 12,011,153 | |
| -1 | -12,011,153 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,011,153.
Example:
1 x 12,011,153 = 12,011,153
and
-1 x -12,011,153 = 12,011,153
Notice both answers equal 12,011,153
With that explanation out of the way, let's continue. Next, we take the number 12,011,153 and divide it by 2:
12,011,153 ÷ 2 = 6,005,576.5
If the quotient is a whole number, then 2 and 6,005,576.5 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 | 12,011,153 | |
| -1 | -12,011,153 |
Now, we try dividing 12,011,153 by 3:
12,011,153 ÷ 3 = 4,003,717.6667
If the quotient is a whole number, then 3 and 4,003,717.6667 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 | 12,011,153 | |
| -1 | -12,011,153 |
Let's try dividing by 4:
12,011,153 ÷ 4 = 3,002,788.25
If the quotient is a whole number, then 4 and 3,002,788.25 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 | 12,011,153 | |
| -1 | 12,011,153 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 389 | 401 | 2,723 | 2,807 | 4,279 | 4,411 | 29,953 | 30,877 | 155,989 | 1,091,923 | 1,715,879 | 12,011,153 |
| -1 | -7 | -11 | -77 | -389 | -401 | -2,723 | -2,807 | -4,279 | -4,411 | -29,953 | -30,877 | -155,989 | -1,091,923 | -1,715,879 | -12,011,153 |
