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 17,270,183, 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 | 17,270,183 | |
| -1 | -17,270,183 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 17,270,183.
Example:
1 x 17,270,183 = 17,270,183
and
-1 x -17,270,183 = 17,270,183
Notice both answers equal 17,270,183
With that explanation out of the way, let's continue. Next, we take the number 17,270,183 and divide it by 2:
17,270,183 ÷ 2 = 8,635,091.5
If the quotient is a whole number, then 2 and 8,635,091.5 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 | 17,270,183 | |
| -1 | -17,270,183 |
Now, we try dividing 17,270,183 by 3:
17,270,183 ÷ 3 = 5,756,727.6667
If the quotient is a whole number, then 3 and 5,756,727.6667 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 | 17,270,183 | |
| -1 | -17,270,183 |
Let's try dividing by 4:
17,270,183 ÷ 4 = 4,317,545.75
If the quotient is a whole number, then 4 and 4,317,545.75 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 | 17,270,183 | |
| -1 | 17,270,183 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 89 | 133 | 623 | 1,459 | 1,691 | 10,213 | 11,837 | 27,721 | 129,851 | 194,047 | 908,957 | 2,467,169 | 17,270,183 |
| -1 | -7 | -19 | -89 | -133 | -623 | -1,459 | -1,691 | -10,213 | -11,837 | -27,721 | -129,851 | -194,047 | -908,957 | -2,467,169 | -17,270,183 |
