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 47,511,065, 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 | 47,511,065 | |
| -1 | -47,511,065 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 47,511,065.
Example:
1 x 47,511,065 = 47,511,065
and
-1 x -47,511,065 = 47,511,065
Notice both answers equal 47,511,065
With that explanation out of the way, let's continue. Next, we take the number 47,511,065 and divide it by 2:
47,511,065 ÷ 2 = 23,755,532.5
If the quotient is a whole number, then 2 and 23,755,532.5 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 | 47,511,065 | |
| -1 | -47,511,065 |
Now, we try dividing 47,511,065 by 3:
47,511,065 ÷ 3 = 15,837,021.6667
If the quotient is a whole number, then 3 and 15,837,021.6667 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 | 47,511,065 | |
| -1 | -47,511,065 |
Let's try dividing by 4:
47,511,065 ÷ 4 = 11,877,766.25
If the quotient is a whole number, then 4 and 11,877,766.25 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 | 47,511,065 | |
| -1 | 47,511,065 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 31 | 35 | 155 | 217 | 1,085 | 43,789 | 218,945 | 306,523 | 1,357,459 | 1,532,615 | 6,787,295 | 9,502,213 | 47,511,065 |
| -1 | -5 | -7 | -31 | -35 | -155 | -217 | -1,085 | -43,789 | -218,945 | -306,523 | -1,357,459 | -1,532,615 | -6,787,295 | -9,502,213 | -47,511,065 |
