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 7,844,347, 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 | 7,844,347 | |
| -1 | -7,844,347 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,844,347.
Example:
1 x 7,844,347 = 7,844,347
and
-1 x -7,844,347 = 7,844,347
Notice both answers equal 7,844,347
With that explanation out of the way, let's continue. Next, we take the number 7,844,347 and divide it by 2:
7,844,347 ÷ 2 = 3,922,173.5
If the quotient is a whole number, then 2 and 3,922,173.5 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 | 7,844,347 | |
| -1 | -7,844,347 |
Now, we try dividing 7,844,347 by 3:
7,844,347 ÷ 3 = 2,614,782.3333
If the quotient is a whole number, then 3 and 2,614,782.3333 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 | 7,844,347 | |
| -1 | -7,844,347 |
Let's try dividing by 4:
7,844,347 ÷ 4 = 1,961,086.75
If the quotient is a whole number, then 4 and 1,961,086.75 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 | 7,844,347 | |
| -1 | 7,844,347 |
If you did it right, you will end up with this table:
| 1 | 7 | 47 | 113 | 211 | 329 | 791 | 1,477 | 5,311 | 9,917 | 23,843 | 37,177 | 69,419 | 166,901 | 1,120,621 | 7,844,347 |
| -1 | -7 | -47 | -113 | -211 | -329 | -791 | -1,477 | -5,311 | -9,917 | -23,843 | -37,177 | -69,419 | -166,901 | -1,120,621 | -7,844,347 |
