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 47,215,133, 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 | 47,215,133 | |
| -1 | -47,215,133 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 47,215,133.
Example:
1 x 47,215,133 = 47,215,133
and
-1 x -47,215,133 = 47,215,133
Notice both answers equal 47,215,133
With that explanation out of the way, let's continue. Next, we take the number 47,215,133 and divide it by 2:
47,215,133 ÷ 2 = 23,607,566.5
If the quotient is a whole number, then 2 and 23,607,566.5 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 | 47,215,133 | |
| -1 | -47,215,133 |
Now, we try dividing 47,215,133 by 3:
47,215,133 ÷ 3 = 15,738,377.6667
If the quotient is a whole number, then 3 and 15,738,377.6667 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 | 47,215,133 | |
| -1 | -47,215,133 |
Let's try dividing by 4:
47,215,133 ÷ 4 = 11,803,783.25
If the quotient is a whole number, then 4 and 11,803,783.25 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 | 47,215,133 | |
| -1 | 47,215,133 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 133 | 151 | 1,057 | 2,351 | 2,869 | 16,457 | 20,083 | 44,669 | 312,683 | 355,001 | 2,485,007 | 6,745,019 | 47,215,133 |
| -1 | -7 | -19 | -133 | -151 | -1,057 | -2,351 | -2,869 | -16,457 | -20,083 | -44,669 | -312,683 | -355,001 | -2,485,007 | -6,745,019 | -47,215,133 |
