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 447,122,005, 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 | 447,122,005 | |
| -1 | -447,122,005 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 447,122,005.
Example:
1 x 447,122,005 = 447,122,005
and
-1 x -447,122,005 = 447,122,005
Notice both answers equal 447,122,005
With that explanation out of the way, let's continue. Next, we take the number 447,122,005 and divide it by 2:
447,122,005 ÷ 2 = 223,561,002.5
If the quotient is a whole number, then 2 and 223,561,002.5 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 | 447,122,005 | |
| -1 | -447,122,005 |
Now, we try dividing 447,122,005 by 3:
447,122,005 ÷ 3 = 149,040,668.3333
If the quotient is a whole number, then 3 and 149,040,668.3333 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 | 447,122,005 | |
| -1 | -447,122,005 |
Let's try dividing by 4:
447,122,005 ÷ 4 = 111,780,501.25
If the quotient is a whole number, then 4 and 111,780,501.25 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 | 447,122,005 | |
| -1 | 447,122,005 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 487 | 2,435 | 5,357 | 16,693 | 26,785 | 83,465 | 183,623 | 918,115 | 8,129,491 | 40,647,455 | 89,424,401 | 447,122,005 |
| -1 | -5 | -11 | -55 | -487 | -2,435 | -5,357 | -16,693 | -26,785 | -83,465 | -183,623 | -918,115 | -8,129,491 | -40,647,455 | -89,424,401 | -447,122,005 |
