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 7,937,039, 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 | 7,937,039 | |
| -1 | -7,937,039 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,937,039.
Example:
1 x 7,937,039 = 7,937,039
and
-1 x -7,937,039 = 7,937,039
Notice both answers equal 7,937,039
With that explanation out of the way, let's continue. Next, we take the number 7,937,039 and divide it by 2:
7,937,039 ÷ 2 = 3,968,519.5
If the quotient is a whole number, then 2 and 3,968,519.5 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 | 7,937,039 | |
| -1 | -7,937,039 |
Now, we try dividing 7,937,039 by 3:
7,937,039 ÷ 3 = 2,645,679.6667
If the quotient is a whole number, then 3 and 2,645,679.6667 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 | 7,937,039 | |
| -1 | -7,937,039 |
Let's try dividing by 4:
7,937,039 ÷ 4 = 1,984,259.75
If the quotient is a whole number, then 4 and 1,984,259.75 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 | 7,937,039 | |
| -1 | 7,937,039 |
If you did it right, you will end up with this table:
| 1 | 11 | 29 | 139 | 179 | 319 | 1,529 | 1,969 | 4,031 | 5,191 | 24,881 | 44,341 | 57,101 | 273,691 | 721,549 | 7,937,039 |
| -1 | -11 | -29 | -139 | -179 | -319 | -1,529 | -1,969 | -4,031 | -5,191 | -24,881 | -44,341 | -57,101 | -273,691 | -721,549 | -7,937,039 |
