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 478,225, 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 | 478,225 | |
| -1 | -478,225 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 478,225.
Example:
1 x 478,225 = 478,225
and
-1 x -478,225 = 478,225
Notice both answers equal 478,225
With that explanation out of the way, let's continue. Next, we take the number 478,225 and divide it by 2:
478,225 ÷ 2 = 239,112.5
If the quotient is a whole number, then 2 and 239,112.5 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 | 478,225 | |
| -1 | -478,225 |
Now, we try dividing 478,225 by 3:
478,225 ÷ 3 = 159,408.3333
If the quotient is a whole number, then 3 and 159,408.3333 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 | 478,225 | |
| -1 | -478,225 |
Let's try dividing by 4:
478,225 ÷ 4 = 119,556.25
If the quotient is a whole number, then 4 and 119,556.25 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 | 478,225 | |
| -1 | 478,225 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 37 | 47 | 55 | 185 | 235 | 275 | 407 | 517 | 925 | 1,175 | 1,739 | 2,035 | 2,585 | 8,695 | 10,175 | 12,925 | 19,129 | 43,475 | 95,645 | 478,225 |
| -1 | -5 | -11 | -25 | -37 | -47 | -55 | -185 | -235 | -275 | -407 | -517 | -925 | -1,175 | -1,739 | -2,035 | -2,585 | -8,695 | -10,175 | -12,925 | -19,129 | -43,475 | -95,645 | -478,225 |
