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 12,000,113, 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 | 12,000,113 | |
| -1 | -12,000,113 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,000,113.
Example:
1 x 12,000,113 = 12,000,113
and
-1 x -12,000,113 = 12,000,113
Notice both answers equal 12,000,113
With that explanation out of the way, let's continue. Next, we take the number 12,000,113 and divide it by 2:
12,000,113 ÷ 2 = 6,000,056.5
If the quotient is a whole number, then 2 and 6,000,056.5 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 | 12,000,113 | |
| -1 | -12,000,113 |
Now, we try dividing 12,000,113 by 3:
12,000,113 ÷ 3 = 4,000,037.6667
If the quotient is a whole number, then 3 and 4,000,037.6667 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 | 12,000,113 | |
| -1 | -12,000,113 |
Let's try dividing by 4:
12,000,113 ÷ 4 = 3,000,028.25
If the quotient is a whole number, then 4 and 3,000,028.25 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 | 12,000,113 | |
| -1 | 12,000,113 |
If you did it right, you will end up with this table:
| 1 | 17 | 29 | 101 | 241 | 493 | 1,717 | 2,929 | 4,097 | 6,989 | 24,341 | 49,793 | 118,813 | 413,797 | 705,889 | 12,000,113 |
| -1 | -17 | -29 | -101 | -241 | -493 | -1,717 | -2,929 | -4,097 | -6,989 | -24,341 | -49,793 | -118,813 | -413,797 | -705,889 | -12,000,113 |
