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 17,550,505, 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 | 17,550,505 | |
| -1 | -17,550,505 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 17,550,505.
Example:
1 x 17,550,505 = 17,550,505
and
-1 x -17,550,505 = 17,550,505
Notice both answers equal 17,550,505
With that explanation out of the way, let's continue. Next, we take the number 17,550,505 and divide it by 2:
17,550,505 ÷ 2 = 8,775,252.5
If the quotient is a whole number, then 2 and 8,775,252.5 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 | 17,550,505 | |
| -1 | -17,550,505 |
Now, we try dividing 17,550,505 by 3:
17,550,505 ÷ 3 = 5,850,168.3333
If the quotient is a whole number, then 3 and 5,850,168.3333 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 | 17,550,505 | |
| -1 | -17,550,505 |
Let's try dividing by 4:
17,550,505 ÷ 4 = 4,387,626.25
If the quotient is a whole number, then 4 and 4,387,626.25 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 | 17,550,505 | |
| -1 | 17,550,505 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 47 | 227 | 235 | 329 | 1,135 | 1,589 | 1,645 | 2,209 | 7,945 | 10,669 | 11,045 | 15,463 | 53,345 | 74,683 | 77,315 | 373,415 | 501,443 | 2,507,215 | 3,510,101 | 17,550,505 |
| -1 | -5 | -7 | -35 | -47 | -227 | -235 | -329 | -1,135 | -1,589 | -1,645 | -2,209 | -7,945 | -10,669 | -11,045 | -15,463 | -53,345 | -74,683 | -77,315 | -373,415 | -501,443 | -2,507,215 | -3,510,101 | -17,550,505 |
