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 10,903,715, 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 | 10,903,715 | |
| -1 | -10,903,715 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,903,715.
Example:
1 x 10,903,715 = 10,903,715
and
-1 x -10,903,715 = 10,903,715
Notice both answers equal 10,903,715
With that explanation out of the way, let's continue. Next, we take the number 10,903,715 and divide it by 2:
10,903,715 ÷ 2 = 5,451,857.5
If the quotient is a whole number, then 2 and 5,451,857.5 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 | 10,903,715 | |
| -1 | -10,903,715 |
Now, we try dividing 10,903,715 by 3:
10,903,715 ÷ 3 = 3,634,571.6667
If the quotient is a whole number, then 3 and 3,634,571.6667 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 | 10,903,715 | |
| -1 | -10,903,715 |
Let's try dividing by 4:
10,903,715 ÷ 4 = 2,725,928.75
If the quotient is a whole number, then 4 and 2,725,928.75 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 | 10,903,715 | |
| -1 | 10,903,715 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 37 | 85 | 185 | 629 | 3,145 | 3,467 | 17,335 | 58,939 | 128,279 | 294,695 | 641,395 | 2,180,743 | 10,903,715 |
| -1 | -5 | -17 | -37 | -85 | -185 | -629 | -3,145 | -3,467 | -17,335 | -58,939 | -128,279 | -294,695 | -641,395 | -2,180,743 | -10,903,715 |
