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 17,058,517, 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 | 17,058,517 | |
| -1 | -17,058,517 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 17,058,517.
Example:
1 x 17,058,517 = 17,058,517
and
-1 x -17,058,517 = 17,058,517
Notice both answers equal 17,058,517
With that explanation out of the way, let's continue. Next, we take the number 17,058,517 and divide it by 2:
17,058,517 ÷ 2 = 8,529,258.5
If the quotient is a whole number, then 2 and 8,529,258.5 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 | 17,058,517 | |
| -1 | -17,058,517 |
Now, we try dividing 17,058,517 by 3:
17,058,517 ÷ 3 = 5,686,172.3333
If the quotient is a whole number, then 3 and 5,686,172.3333 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 | 17,058,517 | |
| -1 | -17,058,517 |
Let's try dividing by 4:
17,058,517 ÷ 4 = 4,264,629.25
If the quotient is a whole number, then 4 and 4,264,629.25 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 | 17,058,517 | |
| -1 | 17,058,517 |
If you did it right, you will end up with this table:
| 1 | 7 | 37 | 49 | 97 | 259 | 679 | 1,813 | 3,589 | 4,753 | 9,409 | 25,123 | 65,863 | 175,861 | 348,133 | 461,041 | 2,436,931 | 17,058,517 |
| -1 | -7 | -37 | -49 | -97 | -259 | -679 | -1,813 | -3,589 | -4,753 | -9,409 | -25,123 | -65,863 | -175,861 | -348,133 | -461,041 | -2,436,931 | -17,058,517 |
