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 47,928,785, 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 | 47,928,785 | |
| -1 | -47,928,785 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 47,928,785.
Example:
1 x 47,928,785 = 47,928,785
and
-1 x -47,928,785 = 47,928,785
Notice both answers equal 47,928,785
With that explanation out of the way, let's continue. Next, we take the number 47,928,785 and divide it by 2:
47,928,785 ÷ 2 = 23,964,392.5
If the quotient is a whole number, then 2 and 23,964,392.5 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 | 47,928,785 | |
| -1 | -47,928,785 |
Now, we try dividing 47,928,785 by 3:
47,928,785 ÷ 3 = 15,976,261.6667
If the quotient is a whole number, then 3 and 15,976,261.6667 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 | 47,928,785 | |
| -1 | -47,928,785 |
Let's try dividing by 4:
47,928,785 ÷ 4 = 11,982,196.25
If the quotient is a whole number, then 4 and 11,982,196.25 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 | 47,928,785 | |
| -1 | 47,928,785 |
If you did it right, you will end up with this table:
| 1 | 5 | 67 | 173 | 335 | 827 | 865 | 4,135 | 11,591 | 55,409 | 57,955 | 143,071 | 277,045 | 715,355 | 9,585,757 | 47,928,785 |
| -1 | -5 | -67 | -173 | -335 | -827 | -865 | -4,135 | -11,591 | -55,409 | -57,955 | -143,071 | -277,045 | -715,355 | -9,585,757 | -47,928,785 |
