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 17,018,855, 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 | 17,018,855 | |
| -1 | -17,018,855 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 17,018,855.
Example:
1 x 17,018,855 = 17,018,855
and
-1 x -17,018,855 = 17,018,855
Notice both answers equal 17,018,855
With that explanation out of the way, let's continue. Next, we take the number 17,018,855 and divide it by 2:
17,018,855 ÷ 2 = 8,509,427.5
If the quotient is a whole number, then 2 and 8,509,427.5 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 | 17,018,855 | |
| -1 | -17,018,855 |
Now, we try dividing 17,018,855 by 3:
17,018,855 ÷ 3 = 5,672,951.6667
If the quotient is a whole number, then 3 and 5,672,951.6667 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 | 17,018,855 | |
| -1 | -17,018,855 |
Let's try dividing by 4:
17,018,855 ÷ 4 = 4,254,713.75
If the quotient is a whole number, then 4 and 4,254,713.75 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 | 17,018,855 | |
| -1 | 17,018,855 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 73 | 365 | 511 | 2,555 | 6,661 | 33,305 | 46,627 | 233,135 | 486,253 | 2,431,265 | 3,403,771 | 17,018,855 |
| -1 | -5 | -7 | -35 | -73 | -365 | -511 | -2,555 | -6,661 | -33,305 | -46,627 | -233,135 | -486,253 | -2,431,265 | -3,403,771 | -17,018,855 |
