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 7,897,571, 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 | 7,897,571 | |
| -1 | -7,897,571 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,897,571.
Example:
1 x 7,897,571 = 7,897,571
and
-1 x -7,897,571 = 7,897,571
Notice both answers equal 7,897,571
With that explanation out of the way, let's continue. Next, we take the number 7,897,571 and divide it by 2:
7,897,571 ÷ 2 = 3,948,785.5
If the quotient is a whole number, then 2 and 3,948,785.5 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 | 7,897,571 | |
| -1 | -7,897,571 |
Now, we try dividing 7,897,571 by 3:
7,897,571 ÷ 3 = 2,632,523.6667
If the quotient is a whole number, then 3 and 2,632,523.6667 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 | 7,897,571 | |
| -1 | -7,897,571 |
Let's try dividing by 4:
7,897,571 ÷ 4 = 1,974,392.75
If the quotient is a whole number, then 4 and 1,974,392.75 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 | 7,897,571 | |
| -1 | 7,897,571 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 157 | 187 | 269 | 1,727 | 2,669 | 2,959 | 4,573 | 29,359 | 42,233 | 50,303 | 464,563 | 717,961 | 7,897,571 |
| -1 | -11 | -17 | -157 | -187 | -269 | -1,727 | -2,669 | -2,959 | -4,573 | -29,359 | -42,233 | -50,303 | -464,563 | -717,961 | -7,897,571 |
