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 16,302,949, 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 | 16,302,949 | |
| -1 | -16,302,949 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,302,949.
Example:
1 x 16,302,949 = 16,302,949
and
-1 x -16,302,949 = 16,302,949
Notice both answers equal 16,302,949
With that explanation out of the way, let's continue. Next, we take the number 16,302,949 and divide it by 2:
16,302,949 ÷ 2 = 8,151,474.5
If the quotient is a whole number, then 2 and 8,151,474.5 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 | 16,302,949 | |
| -1 | -16,302,949 |
Now, we try dividing 16,302,949 by 3:
16,302,949 ÷ 3 = 5,434,316.3333
If the quotient is a whole number, then 3 and 5,434,316.3333 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 | 16,302,949 | |
| -1 | -16,302,949 |
Let's try dividing by 4:
16,302,949 ÷ 4 = 4,075,737.25
If the quotient is a whole number, then 4 and 4,075,737.25 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 | 16,302,949 | |
| -1 | 16,302,949 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 71 | 221 | 923 | 1,039 | 1,207 | 13,507 | 15,691 | 17,663 | 73,769 | 229,619 | 958,997 | 1,254,073 | 16,302,949 |
| -1 | -13 | -17 | -71 | -221 | -923 | -1,039 | -1,207 | -13,507 | -15,691 | -17,663 | -73,769 | -229,619 | -958,997 | -1,254,073 | -16,302,949 |
