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 15,245,243, 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 | 15,245,243 | |
| -1 | -15,245,243 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 15,245,243.
Example:
1 x 15,245,243 = 15,245,243
and
-1 x -15,245,243 = 15,245,243
Notice both answers equal 15,245,243
With that explanation out of the way, let's continue. Next, we take the number 15,245,243 and divide it by 2:
15,245,243 ÷ 2 = 7,622,621.5
If the quotient is a whole number, then 2 and 7,622,621.5 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 | 15,245,243 | |
| -1 | -15,245,243 |
Now, we try dividing 15,245,243 by 3:
15,245,243 ÷ 3 = 5,081,747.6667
If the quotient is a whole number, then 3 and 5,081,747.6667 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 | 15,245,243 | |
| -1 | -15,245,243 |
Let's try dividing by 4:
15,245,243 ÷ 4 = 3,811,310.75
If the quotient is a whole number, then 4 and 3,811,310.75 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 | 15,245,243 | |
| -1 | 15,245,243 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 101 | 221 | 683 | 1,313 | 1,717 | 8,879 | 11,611 | 22,321 | 68,983 | 150,943 | 896,779 | 1,172,711 | 15,245,243 |
| -1 | -13 | -17 | -101 | -221 | -683 | -1,313 | -1,717 | -8,879 | -11,611 | -22,321 | -68,983 | -150,943 | -896,779 | -1,172,711 | -15,245,243 |
