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 481,370,617, 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 | 481,370,617 | |
| -1 | -481,370,617 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 481,370,617.
Example:
1 x 481,370,617 = 481,370,617
and
-1 x -481,370,617 = 481,370,617
Notice both answers equal 481,370,617
With that explanation out of the way, let's continue. Next, we take the number 481,370,617 and divide it by 2:
481,370,617 ÷ 2 = 240,685,308.5
If the quotient is a whole number, then 2 and 240,685,308.5 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 | 481,370,617 | |
| -1 | -481,370,617 |
Now, we try dividing 481,370,617 by 3:
481,370,617 ÷ 3 = 160,456,872.3333
If the quotient is a whole number, then 3 and 160,456,872.3333 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 | 481,370,617 | |
| -1 | -481,370,617 |
Let's try dividing by 4:
481,370,617 ÷ 4 = 120,342,654.25
If the quotient is a whole number, then 4 and 120,342,654.25 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 | 481,370,617 | |
| -1 | 481,370,617 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 91 | 239 | 1,673 | 3,107 | 21,749 | 22,133 | 154,931 | 287,729 | 2,014,103 | 5,289,787 | 37,028,509 | 68,767,231 | 481,370,617 |
| -1 | -7 | -13 | -91 | -239 | -1,673 | -3,107 | -21,749 | -22,133 | -154,931 | -287,729 | -2,014,103 | -5,289,787 | -37,028,509 | -68,767,231 | -481,370,617 |
