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 17,662,271, 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 | 17,662,271 | |
| -1 | -17,662,271 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 17,662,271.
Example:
1 x 17,662,271 = 17,662,271
and
-1 x -17,662,271 = 17,662,271
Notice both answers equal 17,662,271
With that explanation out of the way, let's continue. Next, we take the number 17,662,271 and divide it by 2:
17,662,271 ÷ 2 = 8,831,135.5
If the quotient is a whole number, then 2 and 8,831,135.5 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 | 17,662,271 | |
| -1 | -17,662,271 |
Now, we try dividing 17,662,271 by 3:
17,662,271 ÷ 3 = 5,887,423.6667
If the quotient is a whole number, then 3 and 5,887,423.6667 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 | 17,662,271 | |
| -1 | -17,662,271 |
Let's try dividing by 4:
17,662,271 ÷ 4 = 4,415,567.75
If the quotient is a whole number, then 4 and 4,415,567.75 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 | 17,662,271 | |
| -1 | 17,662,271 |
If you did it right, you will end up with this table:
| 1 | 11 | 47 | 127 | 269 | 517 | 1,397 | 2,959 | 5,969 | 12,643 | 34,163 | 65,659 | 139,073 | 375,793 | 1,605,661 | 17,662,271 |
| -1 | -11 | -47 | -127 | -269 | -517 | -1,397 | -2,959 | -5,969 | -12,643 | -34,163 | -65,659 | -139,073 | -375,793 | -1,605,661 | -17,662,271 |
