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 16,901,717, 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 | 16,901,717 | |
| -1 | -16,901,717 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,901,717.
Example:
1 x 16,901,717 = 16,901,717
and
-1 x -16,901,717 = 16,901,717
Notice both answers equal 16,901,717
With that explanation out of the way, let's continue. Next, we take the number 16,901,717 and divide it by 2:
16,901,717 ÷ 2 = 8,450,858.5
If the quotient is a whole number, then 2 and 8,450,858.5 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 | 16,901,717 | |
| -1 | -16,901,717 |
Now, we try dividing 16,901,717 by 3:
16,901,717 ÷ 3 = 5,633,905.6667
If the quotient is a whole number, then 3 and 5,633,905.6667 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 | 16,901,717 | |
| -1 | -16,901,717 |
Let's try dividing by 4:
16,901,717 ÷ 4 = 4,225,429.25
If the quotient is a whole number, then 4 and 4,225,429.25 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 | 16,901,717 | |
| -1 | 16,901,717 |
If you did it right, you will end up with this table:
| 1 | 7 | 41 | 47 | 49 | 179 | 287 | 329 | 1,253 | 1,927 | 2,009 | 2,303 | 7,339 | 8,413 | 8,771 | 13,489 | 51,373 | 58,891 | 94,423 | 344,933 | 359,611 | 412,237 | 2,414,531 | 16,901,717 |
| -1 | -7 | -41 | -47 | -49 | -179 | -287 | -329 | -1,253 | -1,927 | -2,009 | -2,303 | -7,339 | -8,413 | -8,771 | -13,489 | -51,373 | -58,891 | -94,423 | -344,933 | -359,611 | -412,237 | -2,414,531 | -16,901,717 |
