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 404,243, 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 | 404,243 | |
| -1 | -404,243 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 404,243.
Example:
1 x 404,243 = 404,243
and
-1 x -404,243 = 404,243
Notice both answers equal 404,243
With that explanation out of the way, let's continue. Next, we take the number 404,243 and divide it by 2:
404,243 ÷ 2 = 202,121.5
If the quotient is a whole number, then 2 and 202,121.5 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 | 404,243 | |
| -1 | -404,243 |
Now, we try dividing 404,243 by 3:
404,243 ÷ 3 = 134,747.6667
If the quotient is a whole number, then 3 and 134,747.6667 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 | 404,243 | |
| -1 | -404,243 |
Let's try dividing by 4:
404,243 ÷ 4 = 101,060.75
If the quotient is a whole number, then 4 and 101,060.75 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 | 404,243 | |
| -1 | 404,243 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 43 | 79 | 119 | 301 | 553 | 731 | 1,343 | 3,397 | 5,117 | 9,401 | 23,779 | 57,749 | 404,243 |
| -1 | -7 | -17 | -43 | -79 | -119 | -301 | -553 | -731 | -1,343 | -3,397 | -5,117 | -9,401 | -23,779 | -57,749 | -404,243 |
