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 17,419,193, 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 | 17,419,193 | |
| -1 | -17,419,193 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 17,419,193.
Example:
1 x 17,419,193 = 17,419,193
and
-1 x -17,419,193 = 17,419,193
Notice both answers equal 17,419,193
With that explanation out of the way, let's continue. Next, we take the number 17,419,193 and divide it by 2:
17,419,193 ÷ 2 = 8,709,596.5
If the quotient is a whole number, then 2 and 8,709,596.5 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 | 17,419,193 | |
| -1 | -17,419,193 |
Now, we try dividing 17,419,193 by 3:
17,419,193 ÷ 3 = 5,806,397.6667
If the quotient is a whole number, then 3 and 5,806,397.6667 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 | 17,419,193 | |
| -1 | -17,419,193 |
Let's try dividing by 4:
17,419,193 ÷ 4 = 4,354,798.25
If the quotient is a whole number, then 4 and 4,354,798.25 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 | 17,419,193 | |
| -1 | 17,419,193 |
If you did it right, you will end up with this table:
| 1 | 11 | 37 | 127 | 337 | 407 | 1,397 | 3,707 | 4,699 | 12,469 | 42,799 | 51,689 | 137,159 | 470,789 | 1,583,563 | 17,419,193 |
| -1 | -11 | -37 | -127 | -337 | -407 | -1,397 | -3,707 | -4,699 | -12,469 | -42,799 | -51,689 | -137,159 | -470,789 | -1,583,563 | -17,419,193 |
