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 17,227,795, 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 | 17,227,795 | |
| -1 | -17,227,795 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 17,227,795.
Example:
1 x 17,227,795 = 17,227,795
and
-1 x -17,227,795 = 17,227,795
Notice both answers equal 17,227,795
With that explanation out of the way, let's continue. Next, we take the number 17,227,795 and divide it by 2:
17,227,795 ÷ 2 = 8,613,897.5
If the quotient is a whole number, then 2 and 8,613,897.5 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 | 17,227,795 | |
| -1 | -17,227,795 |
Now, we try dividing 17,227,795 by 3:
17,227,795 ÷ 3 = 5,742,598.3333
If the quotient is a whole number, then 3 and 5,742,598.3333 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 | 17,227,795 | |
| -1 | -17,227,795 |
Let's try dividing by 4:
17,227,795 ÷ 4 = 4,306,948.75
If the quotient is a whole number, then 4 and 4,306,948.75 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 | 17,227,795 | |
| -1 | 17,227,795 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 71 | 355 | 923 | 3,733 | 4,615 | 18,665 | 48,529 | 242,645 | 265,043 | 1,325,215 | 3,445,559 | 17,227,795 |
| -1 | -5 | -13 | -65 | -71 | -355 | -923 | -3,733 | -4,615 | -18,665 | -48,529 | -242,645 | -265,043 | -1,325,215 | -3,445,559 | -17,227,795 |
