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 17,282,947, 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 | 17,282,947 | |
| -1 | -17,282,947 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 17,282,947.
Example:
1 x 17,282,947 = 17,282,947
and
-1 x -17,282,947 = 17,282,947
Notice both answers equal 17,282,947
With that explanation out of the way, let's continue. Next, we take the number 17,282,947 and divide it by 2:
17,282,947 ÷ 2 = 8,641,473.5
If the quotient is a whole number, then 2 and 8,641,473.5 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 | 17,282,947 | |
| -1 | -17,282,947 |
Now, we try dividing 17,282,947 by 3:
17,282,947 ÷ 3 = 5,760,982.3333
If the quotient is a whole number, then 3 and 5,760,982.3333 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 | 17,282,947 | |
| -1 | -17,282,947 |
Let's try dividing by 4:
17,282,947 ÷ 4 = 4,320,736.75
If the quotient is a whole number, then 4 and 4,320,736.75 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 | 17,282,947 | |
| -1 | 17,282,947 |
If you did it right, you will end up with this table:
| 1 | 11 | 43 | 61 | 473 | 599 | 671 | 2,623 | 6,589 | 25,757 | 28,853 | 36,539 | 283,327 | 401,929 | 1,571,177 | 17,282,947 |
| -1 | -11 | -43 | -61 | -473 | -599 | -671 | -2,623 | -6,589 | -25,757 | -28,853 | -36,539 | -283,327 | -401,929 | -1,571,177 | -17,282,947 |
