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 8,703,653, 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 | 8,703,653 | |
| -1 | -8,703,653 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,703,653.
Example:
1 x 8,703,653 = 8,703,653
and
-1 x -8,703,653 = 8,703,653
Notice both answers equal 8,703,653
With that explanation out of the way, let's continue. Next, we take the number 8,703,653 and divide it by 2:
8,703,653 ÷ 2 = 4,351,826.5
If the quotient is a whole number, then 2 and 4,351,826.5 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 | 8,703,653 | |
| -1 | -8,703,653 |
Now, we try dividing 8,703,653 by 3:
8,703,653 ÷ 3 = 2,901,217.6667
If the quotient is a whole number, then 3 and 2,901,217.6667 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 | 8,703,653 | |
| -1 | -8,703,653 |
Let's try dividing by 4:
8,703,653 ÷ 4 = 2,175,913.25
If the quotient is a whole number, then 4 and 2,175,913.25 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 | 8,703,653 | |
| -1 | 8,703,653 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 31 | 133 | 217 | 589 | 2,111 | 4,123 | 14,777 | 40,109 | 65,441 | 280,763 | 458,087 | 1,243,379 | 8,703,653 |
| -1 | -7 | -19 | -31 | -133 | -217 | -589 | -2,111 | -4,123 | -14,777 | -40,109 | -65,441 | -280,763 | -458,087 | -1,243,379 | -8,703,653 |
