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 8,302,217, 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 | 8,302,217 | |
| -1 | -8,302,217 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,302,217.
Example:
1 x 8,302,217 = 8,302,217
and
-1 x -8,302,217 = 8,302,217
Notice both answers equal 8,302,217
With that explanation out of the way, let's continue. Next, we take the number 8,302,217 and divide it by 2:
8,302,217 ÷ 2 = 4,151,108.5
If the quotient is a whole number, then 2 and 4,151,108.5 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 | 8,302,217 | |
| -1 | -8,302,217 |
Now, we try dividing 8,302,217 by 3:
8,302,217 ÷ 3 = 2,767,405.6667
If the quotient is a whole number, then 3 and 2,767,405.6667 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 | 8,302,217 | |
| -1 | -8,302,217 |
Let's try dividing by 4:
8,302,217 ÷ 4 = 2,075,554.25
If the quotient is a whole number, then 4 and 2,075,554.25 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 | 8,302,217 | |
| -1 | 8,302,217 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 49 | 73 | 77 | 211 | 511 | 539 | 803 | 1,477 | 2,321 | 3,577 | 5,621 | 10,339 | 15,403 | 16,247 | 39,347 | 107,821 | 113,729 | 169,433 | 754,747 | 1,186,031 | 8,302,217 |
| -1 | -7 | -11 | -49 | -73 | -77 | -211 | -511 | -539 | -803 | -1,477 | -2,321 | -3,577 | -5,621 | -10,339 | -15,403 | -16,247 | -39,347 | -107,821 | -113,729 | -169,433 | -754,747 | -1,186,031 | -8,302,217 |
