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 481,405,223, 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 | 481,405,223 | |
| -1 | -481,405,223 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 481,405,223.
Example:
1 x 481,405,223 = 481,405,223
and
-1 x -481,405,223 = 481,405,223
Notice both answers equal 481,405,223
With that explanation out of the way, let's continue. Next, we take the number 481,405,223 and divide it by 2:
481,405,223 ÷ 2 = 240,702,611.5
If the quotient is a whole number, then 2 and 240,702,611.5 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 | 481,405,223 | |
| -1 | -481,405,223 |
Now, we try dividing 481,405,223 by 3:
481,405,223 ÷ 3 = 160,468,407.6667
If the quotient is a whole number, then 3 and 160,468,407.6667 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 | 481,405,223 | |
| -1 | -481,405,223 |
Let's try dividing by 4:
481,405,223 ÷ 4 = 120,351,305.75
If the quotient is a whole number, then 4 and 120,351,305.75 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 | 481,405,223 | |
| -1 | 481,405,223 |
If you did it right, you will end up with this table:
| 1 | 13 | 19 | 79 | 247 | 1,027 | 1,501 | 19,513 | 24,671 | 320,723 | 468,749 | 1,949,009 | 6,093,737 | 25,337,117 | 37,031,171 | 481,405,223 |
| -1 | -13 | -19 | -79 | -247 | -1,027 | -1,501 | -19,513 | -24,671 | -320,723 | -468,749 | -1,949,009 | -6,093,737 | -25,337,117 | -37,031,171 | -481,405,223 |
