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 16,151,663, 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 | 16,151,663 | |
| -1 | -16,151,663 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,151,663.
Example:
1 x 16,151,663 = 16,151,663
and
-1 x -16,151,663 = 16,151,663
Notice both answers equal 16,151,663
With that explanation out of the way, let's continue. Next, we take the number 16,151,663 and divide it by 2:
16,151,663 ÷ 2 = 8,075,831.5
If the quotient is a whole number, then 2 and 8,075,831.5 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 | 16,151,663 | |
| -1 | -16,151,663 |
Now, we try dividing 16,151,663 by 3:
16,151,663 ÷ 3 = 5,383,887.6667
If the quotient is a whole number, then 3 and 5,383,887.6667 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 | 16,151,663 | |
| -1 | -16,151,663 |
Let's try dividing by 4:
16,151,663 ÷ 4 = 4,037,915.75
If the quotient is a whole number, then 4 and 4,037,915.75 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 | 16,151,663 | |
| -1 | 16,151,663 |
If you did it right, you will end up with this table:
| 1 | 11 | 41 | 59 | 451 | 607 | 649 | 2,419 | 6,677 | 24,887 | 26,609 | 35,813 | 273,757 | 393,943 | 1,468,333 | 16,151,663 |
| -1 | -11 | -41 | -59 | -451 | -607 | -649 | -2,419 | -6,677 | -24,887 | -26,609 | -35,813 | -273,757 | -393,943 | -1,468,333 | -16,151,663 |
