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 4,066,361, 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 | 4,066,361 | |
| -1 | -4,066,361 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,066,361.
Example:
1 x 4,066,361 = 4,066,361
and
-1 x -4,066,361 = 4,066,361
Notice both answers equal 4,066,361
With that explanation out of the way, let's continue. Next, we take the number 4,066,361 and divide it by 2:
4,066,361 ÷ 2 = 2,033,180.5
If the quotient is a whole number, then 2 and 2,033,180.5 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 | 4,066,361 | |
| -1 | -4,066,361 |
Now, we try dividing 4,066,361 by 3:
4,066,361 ÷ 3 = 1,355,453.6667
If the quotient is a whole number, then 3 and 1,355,453.6667 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 | 4,066,361 | |
| -1 | -4,066,361 |
Let's try dividing by 4:
4,066,361 ÷ 4 = 1,016,590.25
If the quotient is a whole number, then 4 and 1,016,590.25 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 | 4,066,361 | |
| -1 | 4,066,361 |
If you did it right, you will end up with this table:
| 1 | 13 | 19 | 101 | 163 | 247 | 1,313 | 1,919 | 2,119 | 3,097 | 16,463 | 24,947 | 40,261 | 214,019 | 312,797 | 4,066,361 |
| -1 | -13 | -19 | -101 | -163 | -247 | -1,313 | -1,919 | -2,119 | -3,097 | -16,463 | -24,947 | -40,261 | -214,019 | -312,797 | -4,066,361 |
