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 47,040,065, 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 | 47,040,065 | |
| -1 | -47,040,065 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 47,040,065.
Example:
1 x 47,040,065 = 47,040,065
and
-1 x -47,040,065 = 47,040,065
Notice both answers equal 47,040,065
With that explanation out of the way, let's continue. Next, we take the number 47,040,065 and divide it by 2:
47,040,065 ÷ 2 = 23,520,032.5
If the quotient is a whole number, then 2 and 23,520,032.5 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 | 47,040,065 | |
| -1 | -47,040,065 |
Now, we try dividing 47,040,065 by 3:
47,040,065 ÷ 3 = 15,680,021.6667
If the quotient is a whole number, then 3 and 15,680,021.6667 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 | 47,040,065 | |
| -1 | -47,040,065 |
Let's try dividing by 4:
47,040,065 ÷ 4 = 11,760,016.25
If the quotient is a whole number, then 4 and 11,760,016.25 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 | 47,040,065 | |
| -1 | 47,040,065 |
If you did it right, you will end up with this table:
| 1 | 5 | 43 | 215 | 331 | 661 | 1,655 | 3,305 | 14,233 | 28,423 | 71,165 | 142,115 | 218,791 | 1,093,955 | 9,408,013 | 47,040,065 |
| -1 | -5 | -43 | -215 | -331 | -661 | -1,655 | -3,305 | -14,233 | -28,423 | -71,165 | -142,115 | -218,791 | -1,093,955 | -9,408,013 | -47,040,065 |
