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 16,223,441, 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 | 16,223,441 | |
| -1 | -16,223,441 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,223,441.
Example:
1 x 16,223,441 = 16,223,441
and
-1 x -16,223,441 = 16,223,441
Notice both answers equal 16,223,441
With that explanation out of the way, let's continue. Next, we take the number 16,223,441 and divide it by 2:
16,223,441 ÷ 2 = 8,111,720.5
If the quotient is a whole number, then 2 and 8,111,720.5 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 | 16,223,441 | |
| -1 | -16,223,441 |
Now, we try dividing 16,223,441 by 3:
16,223,441 ÷ 3 = 5,407,813.6667
If the quotient is a whole number, then 3 and 5,407,813.6667 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 | 16,223,441 | |
| -1 | -16,223,441 |
Let's try dividing by 4:
16,223,441 ÷ 4 = 4,055,860.25
If the quotient is a whole number, then 4 and 4,055,860.25 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 | 16,223,441 | |
| -1 | 16,223,441 |
If you did it right, you will end up with this table:
| 1 | 13 | 23 | 29 | 299 | 377 | 667 | 1,871 | 8,671 | 24,323 | 43,033 | 54,259 | 559,429 | 705,367 | 1,247,957 | 16,223,441 |
| -1 | -13 | -23 | -29 | -299 | -377 | -667 | -1,871 | -8,671 | -24,323 | -43,033 | -54,259 | -559,429 | -705,367 | -1,247,957 | -16,223,441 |
