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 16,536,653, 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 | 16,536,653 | |
| -1 | -16,536,653 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,536,653.
Example:
1 x 16,536,653 = 16,536,653
and
-1 x -16,536,653 = 16,536,653
Notice both answers equal 16,536,653
With that explanation out of the way, let's continue. Next, we take the number 16,536,653 and divide it by 2:
16,536,653 ÷ 2 = 8,268,326.5
If the quotient is a whole number, then 2 and 8,268,326.5 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 | 16,536,653 | |
| -1 | -16,536,653 |
Now, we try dividing 16,536,653 by 3:
16,536,653 ÷ 3 = 5,512,217.6667
If the quotient is a whole number, then 3 and 5,512,217.6667 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 | 16,536,653 | |
| -1 | -16,536,653 |
Let's try dividing by 4:
16,536,653 ÷ 4 = 4,134,163.25
If the quotient is a whole number, then 4 and 4,134,163.25 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 | 16,536,653 | |
| -1 | 16,536,653 |
If you did it right, you will end up with this table:
| 1 | 7 | 41 | 157 | 287 | 367 | 1,099 | 2,569 | 6,437 | 15,047 | 45,059 | 57,619 | 105,329 | 403,333 | 2,362,379 | 16,536,653 |
| -1 | -7 | -41 | -157 | -287 | -367 | -1,099 | -2,569 | -6,437 | -15,047 | -45,059 | -57,619 | -105,329 | -403,333 | -2,362,379 | -16,536,653 |
