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 16,751,647, 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 | 16,751,647 | |
| -1 | -16,751,647 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,751,647.
Example:
1 x 16,751,647 = 16,751,647
and
-1 x -16,751,647 = 16,751,647
Notice both answers equal 16,751,647
With that explanation out of the way, let's continue. Next, we take the number 16,751,647 and divide it by 2:
16,751,647 ÷ 2 = 8,375,823.5
If the quotient is a whole number, then 2 and 8,375,823.5 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 | 16,751,647 | |
| -1 | -16,751,647 |
Now, we try dividing 16,751,647 by 3:
16,751,647 ÷ 3 = 5,583,882.3333
If the quotient is a whole number, then 3 and 5,583,882.3333 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 | 16,751,647 | |
| -1 | -16,751,647 |
Let's try dividing by 4:
16,751,647 ÷ 4 = 4,187,911.75
If the quotient is a whole number, then 4 and 4,187,911.75 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 | 16,751,647 | |
| -1 | 16,751,647 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 29 | 187 | 319 | 493 | 3,089 | 5,423 | 33,979 | 52,513 | 89,581 | 577,643 | 985,391 | 1,522,877 | 16,751,647 |
| -1 | -11 | -17 | -29 | -187 | -319 | -493 | -3,089 | -5,423 | -33,979 | -52,513 | -89,581 | -577,643 | -985,391 | -1,522,877 | -16,751,647 |
