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 17,098,655, 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 | 17,098,655 | |
| -1 | -17,098,655 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 17,098,655.
Example:
1 x 17,098,655 = 17,098,655
and
-1 x -17,098,655 = 17,098,655
Notice both answers equal 17,098,655
With that explanation out of the way, let's continue. Next, we take the number 17,098,655 and divide it by 2:
17,098,655 ÷ 2 = 8,549,327.5
If the quotient is a whole number, then 2 and 8,549,327.5 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 | 17,098,655 | |
| -1 | -17,098,655 |
Now, we try dividing 17,098,655 by 3:
17,098,655 ÷ 3 = 5,699,551.6667
If the quotient is a whole number, then 3 and 5,699,551.6667 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 | 17,098,655 | |
| -1 | -17,098,655 |
Let's try dividing by 4:
17,098,655 ÷ 4 = 4,274,663.75
If the quotient is a whole number, then 4 and 4,274,663.75 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 | 17,098,655 | |
| -1 | 17,098,655 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 457 | 1,069 | 2,285 | 3,199 | 5,345 | 7,483 | 15,995 | 37,415 | 488,533 | 2,442,665 | 3,419,731 | 17,098,655 |
| -1 | -5 | -7 | -35 | -457 | -1,069 | -2,285 | -3,199 | -5,345 | -7,483 | -15,995 | -37,415 | -488,533 | -2,442,665 | -3,419,731 | -17,098,655 |
