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 480,815, 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 | 480,815 | |
| -1 | -480,815 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 480,815.
Example:
1 x 480,815 = 480,815
and
-1 x -480,815 = 480,815
Notice both answers equal 480,815
With that explanation out of the way, let's continue. Next, we take the number 480,815 and divide it by 2:
480,815 ÷ 2 = 240,407.5
If the quotient is a whole number, then 2 and 240,407.5 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 | 480,815 | |
| -1 | -480,815 |
Now, we try dividing 480,815 by 3:
480,815 ÷ 3 = 160,271.6667
If the quotient is a whole number, then 3 and 160,271.6667 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 | 480,815 | |
| -1 | -480,815 |
Let's try dividing by 4:
480,815 ÷ 4 = 120,203.75
If the quotient is a whole number, then 4 and 120,203.75 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 | 480,815 | |
| -1 | 480,815 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 37 | 113 | 115 | 185 | 565 | 851 | 2,599 | 4,181 | 4,255 | 12,995 | 20,905 | 96,163 | 480,815 |
| -1 | -5 | -23 | -37 | -113 | -115 | -185 | -565 | -851 | -2,599 | -4,181 | -4,255 | -12,995 | -20,905 | -96,163 | -480,815 |
