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 16,626,533, 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 | 16,626,533 | |
| -1 | -16,626,533 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,626,533.
Example:
1 x 16,626,533 = 16,626,533
and
-1 x -16,626,533 = 16,626,533
Notice both answers equal 16,626,533
With that explanation out of the way, let's continue. Next, we take the number 16,626,533 and divide it by 2:
16,626,533 ÷ 2 = 8,313,266.5
If the quotient is a whole number, then 2 and 8,313,266.5 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 | 16,626,533 | |
| -1 | -16,626,533 |
Now, we try dividing 16,626,533 by 3:
16,626,533 ÷ 3 = 5,542,177.6667
If the quotient is a whole number, then 3 and 5,542,177.6667 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 | 16,626,533 | |
| -1 | -16,626,533 |
Let's try dividing by 4:
16,626,533 ÷ 4 = 4,156,633.25
If the quotient is a whole number, then 4 and 4,156,633.25 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 | 16,626,533 | |
| -1 | 16,626,533 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 49 | 77 | 109 | 283 | 539 | 763 | 1,199 | 1,981 | 3,113 | 5,341 | 8,393 | 13,867 | 21,791 | 30,847 | 58,751 | 152,537 | 215,929 | 339,317 | 1,511,503 | 2,375,219 | 16,626,533 |
| -1 | -7 | -11 | -49 | -77 | -109 | -283 | -539 | -763 | -1,199 | -1,981 | -3,113 | -5,341 | -8,393 | -13,867 | -21,791 | -30,847 | -58,751 | -152,537 | -215,929 | -339,317 | -1,511,503 | -2,375,219 | -16,626,533 |
