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 16,614,533, 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 | 16,614,533 | |
| -1 | -16,614,533 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,614,533.
Example:
1 x 16,614,533 = 16,614,533
and
-1 x -16,614,533 = 16,614,533
Notice both answers equal 16,614,533
With that explanation out of the way, let's continue. Next, we take the number 16,614,533 and divide it by 2:
16,614,533 ÷ 2 = 8,307,266.5
If the quotient is a whole number, then 2 and 8,307,266.5 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 | 16,614,533 | |
| -1 | -16,614,533 |
Now, we try dividing 16,614,533 by 3:
16,614,533 ÷ 3 = 5,538,177.6667
If the quotient is a whole number, then 3 and 5,538,177.6667 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 | 16,614,533 | |
| -1 | -16,614,533 |
Let's try dividing by 4:
16,614,533 ÷ 4 = 4,153,633.25
If the quotient is a whole number, then 4 and 4,153,633.25 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 | 16,614,533 | |
| -1 | 16,614,533 |
If you did it right, you will end up with this table:
| 1 | 13 | 23 | 181 | 299 | 307 | 2,353 | 3,991 | 4,163 | 7,061 | 54,119 | 55,567 | 91,793 | 722,371 | 1,278,041 | 16,614,533 |
| -1 | -13 | -23 | -181 | -299 | -307 | -2,353 | -3,991 | -4,163 | -7,061 | -54,119 | -55,567 | -91,793 | -722,371 | -1,278,041 | -16,614,533 |
