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 404,225, 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 | 404,225 | |
| -1 | -404,225 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 404,225.
Example:
1 x 404,225 = 404,225
and
-1 x -404,225 = 404,225
Notice both answers equal 404,225
With that explanation out of the way, let's continue. Next, we take the number 404,225 and divide it by 2:
404,225 ÷ 2 = 202,112.5
If the quotient is a whole number, then 2 and 202,112.5 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 | 404,225 | |
| -1 | -404,225 |
Now, we try dividing 404,225 by 3:
404,225 ÷ 3 = 134,741.6667
If the quotient is a whole number, then 3 and 134,741.6667 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 | 404,225 | |
| -1 | -404,225 |
Let's try dividing by 4:
404,225 ÷ 4 = 101,056.25
If the quotient is a whole number, then 4 and 101,056.25 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 | 404,225 | |
| -1 | 404,225 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 23 | 25 | 37 | 95 | 115 | 185 | 437 | 475 | 575 | 703 | 851 | 925 | 2,185 | 3,515 | 4,255 | 10,925 | 16,169 | 17,575 | 21,275 | 80,845 | 404,225 |
| -1 | -5 | -19 | -23 | -25 | -37 | -95 | -115 | -185 | -437 | -475 | -575 | -703 | -851 | -925 | -2,185 | -3,515 | -4,255 | -10,925 | -16,169 | -17,575 | -21,275 | -80,845 | -404,225 |
