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 15,263,435, 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 | 15,263,435 | |
| -1 | -15,263,435 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 15,263,435.
Example:
1 x 15,263,435 = 15,263,435
and
-1 x -15,263,435 = 15,263,435
Notice both answers equal 15,263,435
With that explanation out of the way, let's continue. Next, we take the number 15,263,435 and divide it by 2:
15,263,435 ÷ 2 = 7,631,717.5
If the quotient is a whole number, then 2 and 7,631,717.5 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 | 15,263,435 | |
| -1 | -15,263,435 |
Now, we try dividing 15,263,435 by 3:
15,263,435 ÷ 3 = 5,087,811.6667
If the quotient is a whole number, then 3 and 5,087,811.6667 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 | 15,263,435 | |
| -1 | -15,263,435 |
Let's try dividing by 4:
15,263,435 ÷ 4 = 3,815,858.75
If the quotient is a whole number, then 4 and 3,815,858.75 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 | 15,263,435 | |
| -1 | 15,263,435 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 97 | 485 | 1,067 | 2,861 | 5,335 | 14,305 | 31,471 | 157,355 | 277,517 | 1,387,585 | 3,052,687 | 15,263,435 |
| -1 | -5 | -11 | -55 | -97 | -485 | -1,067 | -2,861 | -5,335 | -14,305 | -31,471 | -157,355 | -277,517 | -1,387,585 | -3,052,687 | -15,263,435 |
