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 15,206,863, 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 | 15,206,863 | |
| -1 | -15,206,863 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 15,206,863.
Example:
1 x 15,206,863 = 15,206,863
and
-1 x -15,206,863 = 15,206,863
Notice both answers equal 15,206,863
With that explanation out of the way, let's continue. Next, we take the number 15,206,863 and divide it by 2:
15,206,863 ÷ 2 = 7,603,431.5
If the quotient is a whole number, then 2 and 7,603,431.5 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 | 15,206,863 | |
| -1 | -15,206,863 |
Now, we try dividing 15,206,863 by 3:
15,206,863 ÷ 3 = 5,068,954.3333
If the quotient is a whole number, then 3 and 5,068,954.3333 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 | 15,206,863 | |
| -1 | -15,206,863 |
Let's try dividing by 4:
15,206,863 ÷ 4 = 3,801,715.75
If the quotient is a whole number, then 4 and 3,801,715.75 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 | 15,206,863 | |
| -1 | 15,206,863 |
If you did it right, you will end up with this table:
| 1 | 7 | 101 | 137 | 157 | 707 | 959 | 1,099 | 13,837 | 15,857 | 21,509 | 96,859 | 110,999 | 150,563 | 2,172,409 | 15,206,863 |
| -1 | -7 | -101 | -137 | -157 | -707 | -959 | -1,099 | -13,837 | -15,857 | -21,509 | -96,859 | -110,999 | -150,563 | -2,172,409 | -15,206,863 |
