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 16,247,015, 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 | 16,247,015 | |
| -1 | -16,247,015 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,247,015.
Example:
1 x 16,247,015 = 16,247,015
and
-1 x -16,247,015 = 16,247,015
Notice both answers equal 16,247,015
With that explanation out of the way, let's continue. Next, we take the number 16,247,015 and divide it by 2:
16,247,015 ÷ 2 = 8,123,507.5
If the quotient is a whole number, then 2 and 8,123,507.5 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 | 16,247,015 | |
| -1 | -16,247,015 |
Now, we try dividing 16,247,015 by 3:
16,247,015 ÷ 3 = 5,415,671.6667
If the quotient is a whole number, then 3 and 5,415,671.6667 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 | 16,247,015 | |
| -1 | -16,247,015 |
Let's try dividing by 4:
16,247,015 ÷ 4 = 4,061,753.75
If the quotient is a whole number, then 4 and 4,061,753.75 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 | 16,247,015 | |
| -1 | 16,247,015 |
If you did it right, you will end up with this table:
| 1 | 5 | 97 | 139 | 241 | 485 | 695 | 1,205 | 13,483 | 23,377 | 33,499 | 67,415 | 116,885 | 167,495 | 3,249,403 | 16,247,015 |
| -1 | -5 | -97 | -139 | -241 | -485 | -695 | -1,205 | -13,483 | -23,377 | -33,499 | -67,415 | -116,885 | -167,495 | -3,249,403 | -16,247,015 |
