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 481,260,715, 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 | 481,260,715 | |
| -1 | -481,260,715 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 481,260,715.
Example:
1 x 481,260,715 = 481,260,715
and
-1 x -481,260,715 = 481,260,715
Notice both answers equal 481,260,715
With that explanation out of the way, let's continue. Next, we take the number 481,260,715 and divide it by 2:
481,260,715 ÷ 2 = 240,630,357.5
If the quotient is a whole number, then 2 and 240,630,357.5 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 | 481,260,715 | |
| -1 | -481,260,715 |
Now, we try dividing 481,260,715 by 3:
481,260,715 ÷ 3 = 160,420,238.3333
If the quotient is a whole number, then 3 and 160,420,238.3333 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 | 481,260,715 | |
| -1 | -481,260,715 |
Let's try dividing by 4:
481,260,715 ÷ 4 = 120,315,178.75
If the quotient is a whole number, then 4 and 120,315,178.75 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 | 481,260,715 | |
| -1 | 481,260,715 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 1,697 | 4,363 | 8,485 | 21,815 | 22,061 | 56,719 | 110,305 | 283,595 | 7,404,011 | 37,020,055 | 96,252,143 | 481,260,715 |
| -1 | -5 | -13 | -65 | -1,697 | -4,363 | -8,485 | -21,815 | -22,061 | -56,719 | -110,305 | -283,595 | -7,404,011 | -37,020,055 | -96,252,143 | -481,260,715 |
