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 6,897,209, 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 | 6,897,209 | |
| -1 | -6,897,209 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 6,897,209.
Example:
1 x 6,897,209 = 6,897,209
and
-1 x -6,897,209 = 6,897,209
Notice both answers equal 6,897,209
With that explanation out of the way, let's continue. Next, we take the number 6,897,209 and divide it by 2:
6,897,209 ÷ 2 = 3,448,604.5
If the quotient is a whole number, then 2 and 3,448,604.5 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 | 6,897,209 | |
| -1 | -6,897,209 |
Now, we try dividing 6,897,209 by 3:
6,897,209 ÷ 3 = 2,299,069.6667
If the quotient is a whole number, then 3 and 2,299,069.6667 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 | 6,897,209 | |
| -1 | -6,897,209 |
Let's try dividing by 4:
6,897,209 ÷ 4 = 1,724,302.25
If the quotient is a whole number, then 4 and 1,724,302.25 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 | 6,897,209 | |
| -1 | 6,897,209 |
If you did it right, you will end up with this table:
| 1 | 11 | 19 | 61 | 209 | 541 | 671 | 1,159 | 5,951 | 10,279 | 12,749 | 33,001 | 113,069 | 363,011 | 627,019 | 6,897,209 |
| -1 | -11 | -19 | -61 | -209 | -541 | -671 | -1,159 | -5,951 | -10,279 | -12,749 | -33,001 | -113,069 | -363,011 | -627,019 | -6,897,209 |
