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 471,612,089, 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 | 471,612,089 | |
| -1 | -471,612,089 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 471,612,089.
Example:
1 x 471,612,089 = 471,612,089
and
-1 x -471,612,089 = 471,612,089
Notice both answers equal 471,612,089
With that explanation out of the way, let's continue. Next, we take the number 471,612,089 and divide it by 2:
471,612,089 ÷ 2 = 235,806,044.5
If the quotient is a whole number, then 2 and 235,806,044.5 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 | 471,612,089 | |
| -1 | -471,612,089 |
Now, we try dividing 471,612,089 by 3:
471,612,089 ÷ 3 = 157,204,029.6667
If the quotient is a whole number, then 3 and 157,204,029.6667 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 | 471,612,089 | |
| -1 | -471,612,089 |
Let's try dividing by 4:
471,612,089 ÷ 4 = 117,903,022.25
If the quotient is a whole number, then 4 and 117,903,022.25 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 | 471,612,089 | |
| -1 | 471,612,089 |
If you did it right, you will end up with this table:
| 1 | 13 | 43 | 449 | 559 | 1,879 | 5,837 | 19,307 | 24,427 | 80,797 | 250,991 | 843,671 | 1,050,361 | 10,967,723 | 36,277,853 | 471,612,089 |
| -1 | -13 | -43 | -449 | -559 | -1,879 | -5,837 | -19,307 | -24,427 | -80,797 | -250,991 | -843,671 | -1,050,361 | -10,967,723 | -36,277,853 | -471,612,089 |
