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 16,010,617, 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 | 16,010,617 | |
| -1 | -16,010,617 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,010,617.
Example:
1 x 16,010,617 = 16,010,617
and
-1 x -16,010,617 = 16,010,617
Notice both answers equal 16,010,617
With that explanation out of the way, let's continue. Next, we take the number 16,010,617 and divide it by 2:
16,010,617 ÷ 2 = 8,005,308.5
If the quotient is a whole number, then 2 and 8,005,308.5 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 | 16,010,617 | |
| -1 | -16,010,617 |
Now, we try dividing 16,010,617 by 3:
16,010,617 ÷ 3 = 5,336,872.3333
If the quotient is a whole number, then 3 and 5,336,872.3333 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 | 16,010,617 | |
| -1 | -16,010,617 |
Let's try dividing by 4:
16,010,617 ÷ 4 = 4,002,654.25
If the quotient is a whole number, then 4 and 4,002,654.25 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 | 16,010,617 | |
| -1 | 16,010,617 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 83 | 119 | 581 | 1,411 | 1,621 | 9,877 | 11,347 | 27,557 | 134,543 | 192,899 | 941,801 | 2,287,231 | 16,010,617 |
| -1 | -7 | -17 | -83 | -119 | -581 | -1,411 | -1,621 | -9,877 | -11,347 | -27,557 | -134,543 | -192,899 | -941,801 | -2,287,231 | -16,010,617 |
