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 480,281,735, 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 | 480,281,735 | |
| -1 | -480,281,735 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 480,281,735.
Example:
1 x 480,281,735 = 480,281,735
and
-1 x -480,281,735 = 480,281,735
Notice both answers equal 480,281,735
With that explanation out of the way, let's continue. Next, we take the number 480,281,735 and divide it by 2:
480,281,735 ÷ 2 = 240,140,867.5
If the quotient is a whole number, then 2 and 240,140,867.5 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 | 480,281,735 | |
| -1 | -480,281,735 |
Now, we try dividing 480,281,735 by 3:
480,281,735 ÷ 3 = 160,093,911.6667
If the quotient is a whole number, then 3 and 160,093,911.6667 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 | 480,281,735 | |
| -1 | -480,281,735 |
Let's try dividing by 4:
480,281,735 ÷ 4 = 120,070,433.75
If the quotient is a whole number, then 4 and 120,070,433.75 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 | 480,281,735 | |
| -1 | 480,281,735 |
If you did it right, you will end up with this table:
| 1 | 5 | 173 | 233 | 865 | 1,165 | 2,383 | 11,915 | 40,309 | 201,545 | 412,259 | 555,239 | 2,061,295 | 2,776,195 | 96,056,347 | 480,281,735 |
| -1 | -5 | -173 | -233 | -865 | -1,165 | -2,383 | -11,915 | -40,309 | -201,545 | -412,259 | -555,239 | -2,061,295 | -2,776,195 | -96,056,347 | -480,281,735 |
