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 16,822,015, 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 | 16,822,015 | |
| -1 | -16,822,015 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,822,015.
Example:
1 x 16,822,015 = 16,822,015
and
-1 x -16,822,015 = 16,822,015
Notice both answers equal 16,822,015
With that explanation out of the way, let's continue. Next, we take the number 16,822,015 and divide it by 2:
16,822,015 ÷ 2 = 8,411,007.5
If the quotient is a whole number, then 2 and 8,411,007.5 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 | 16,822,015 | |
| -1 | -16,822,015 |
Now, we try dividing 16,822,015 by 3:
16,822,015 ÷ 3 = 5,607,338.3333
If the quotient is a whole number, then 3 and 5,607,338.3333 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 | 16,822,015 | |
| -1 | -16,822,015 |
Let's try dividing by 4:
16,822,015 ÷ 4 = 4,205,503.75
If the quotient is a whole number, then 4 and 4,205,503.75 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 | 16,822,015 | |
| -1 | 16,822,015 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 239 | 1,195 | 1,673 | 2,011 | 8,365 | 10,055 | 14,077 | 70,385 | 480,629 | 2,403,145 | 3,364,403 | 16,822,015 |
| -1 | -5 | -7 | -35 | -239 | -1,195 | -1,673 | -2,011 | -8,365 | -10,055 | -14,077 | -70,385 | -480,629 | -2,403,145 | -3,364,403 | -16,822,015 |
