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 12,406,075, 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 | 12,406,075 | |
| -1 | -12,406,075 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,406,075.
Example:
1 x 12,406,075 = 12,406,075
and
-1 x -12,406,075 = 12,406,075
Notice both answers equal 12,406,075
With that explanation out of the way, let's continue. Next, we take the number 12,406,075 and divide it by 2:
12,406,075 ÷ 2 = 6,203,037.5
If the quotient is a whole number, then 2 and 6,203,037.5 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 | 12,406,075 | |
| -1 | -12,406,075 |
Now, we try dividing 12,406,075 by 3:
12,406,075 ÷ 3 = 4,135,358.3333
If the quotient is a whole number, then 3 and 4,135,358.3333 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 | 12,406,075 | |
| -1 | -12,406,075 |
Let's try dividing by 4:
12,406,075 ÷ 4 = 3,101,518.75
If the quotient is a whole number, then 4 and 3,101,518.75 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 | 12,406,075 | |
| -1 | 12,406,075 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 55 | 197 | 229 | 275 | 985 | 1,145 | 2,167 | 2,519 | 4,925 | 5,725 | 10,835 | 12,595 | 45,113 | 54,175 | 62,975 | 225,565 | 496,243 | 1,127,825 | 2,481,215 | 12,406,075 |
| -1 | -5 | -11 | -25 | -55 | -197 | -229 | -275 | -985 | -1,145 | -2,167 | -2,519 | -4,925 | -5,725 | -10,835 | -12,595 | -45,113 | -54,175 | -62,975 | -225,565 | -496,243 | -1,127,825 | -2,481,215 | -12,406,075 |
