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 12,186,061, 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 | 12,186,061 | |
| -1 | -12,186,061 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,186,061.
Example:
1 x 12,186,061 = 12,186,061
and
-1 x -12,186,061 = 12,186,061
Notice both answers equal 12,186,061
With that explanation out of the way, let's continue. Next, we take the number 12,186,061 and divide it by 2:
12,186,061 ÷ 2 = 6,093,030.5
If the quotient is a whole number, then 2 and 6,093,030.5 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 | 12,186,061 | |
| -1 | -12,186,061 |
Now, we try dividing 12,186,061 by 3:
12,186,061 ÷ 3 = 4,062,020.3333
If the quotient is a whole number, then 3 and 4,062,020.3333 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 | 12,186,061 | |
| -1 | -12,186,061 |
Let's try dividing by 4:
12,186,061 ÷ 4 = 3,046,515.25
If the quotient is a whole number, then 4 and 3,046,515.25 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 | 12,186,061 | |
| -1 | 12,186,061 |
If you did it right, you will end up with this table:
| 1 | 29 | 37 | 41 | 277 | 1,073 | 1,189 | 1,517 | 8,033 | 10,249 | 11,357 | 43,993 | 297,221 | 329,353 | 420,209 | 12,186,061 |
| -1 | -29 | -37 | -41 | -277 | -1,073 | -1,189 | -1,517 | -8,033 | -10,249 | -11,357 | -43,993 | -297,221 | -329,353 | -420,209 | -12,186,061 |
