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 16,541,369, 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 | 16,541,369 | |
| -1 | -16,541,369 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,541,369.
Example:
1 x 16,541,369 = 16,541,369
and
-1 x -16,541,369 = 16,541,369
Notice both answers equal 16,541,369
With that explanation out of the way, let's continue. Next, we take the number 16,541,369 and divide it by 2:
16,541,369 ÷ 2 = 8,270,684.5
If the quotient is a whole number, then 2 and 8,270,684.5 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 | 16,541,369 | |
| -1 | -16,541,369 |
Now, we try dividing 16,541,369 by 3:
16,541,369 ÷ 3 = 5,513,789.6667
If the quotient is a whole number, then 3 and 5,513,789.6667 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 | 16,541,369 | |
| -1 | -16,541,369 |
Let's try dividing by 4:
16,541,369 ÷ 4 = 4,135,342.25
If the quotient is a whole number, then 4 and 4,135,342.25 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 | 16,541,369 | |
| -1 | 16,541,369 |
If you did it right, you will end up with this table:
| 1 | 13 | 43 | 127 | 233 | 559 | 1,651 | 3,029 | 5,461 | 10,019 | 29,591 | 70,993 | 130,247 | 384,683 | 1,272,413 | 16,541,369 |
| -1 | -13 | -43 | -127 | -233 | -559 | -1,651 | -3,029 | -5,461 | -10,019 | -29,591 | -70,993 | -130,247 | -384,683 | -1,272,413 | -16,541,369 |
