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 15,933,047, 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 | 15,933,047 | |
| -1 | -15,933,047 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 15,933,047.
Example:
1 x 15,933,047 = 15,933,047
and
-1 x -15,933,047 = 15,933,047
Notice both answers equal 15,933,047
With that explanation out of the way, let's continue. Next, we take the number 15,933,047 and divide it by 2:
15,933,047 ÷ 2 = 7,966,523.5
If the quotient is a whole number, then 2 and 7,966,523.5 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 | 15,933,047 | |
| -1 | -15,933,047 |
Now, we try dividing 15,933,047 by 3:
15,933,047 ÷ 3 = 5,311,015.6667
If the quotient is a whole number, then 3 and 5,311,015.6667 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 | 15,933,047 | |
| -1 | -15,933,047 |
Let's try dividing by 4:
15,933,047 ÷ 4 = 3,983,261.75
If the quotient is a whole number, then 4 and 3,983,261.75 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 | 15,933,047 | |
| -1 | 15,933,047 |
If you did it right, you will end up with this table:
| 1 | 13 | 47 | 89 | 293 | 611 | 1,157 | 3,809 | 4,183 | 13,771 | 26,077 | 54,379 | 179,023 | 339,001 | 1,225,619 | 15,933,047 |
| -1 | -13 | -47 | -89 | -293 | -611 | -1,157 | -3,809 | -4,183 | -13,771 | -26,077 | -54,379 | -179,023 | -339,001 | -1,225,619 | -15,933,047 |
