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 7,701,715, 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 | 7,701,715 | |
| -1 | -7,701,715 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,701,715.
Example:
1 x 7,701,715 = 7,701,715
and
-1 x -7,701,715 = 7,701,715
Notice both answers equal 7,701,715
With that explanation out of the way, let's continue. Next, we take the number 7,701,715 and divide it by 2:
7,701,715 ÷ 2 = 3,850,857.5
If the quotient is a whole number, then 2 and 3,850,857.5 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 | 7,701,715 | |
| -1 | -7,701,715 |
Now, we try dividing 7,701,715 by 3:
7,701,715 ÷ 3 = 2,567,238.3333
If the quotient is a whole number, then 3 and 2,567,238.3333 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 | 7,701,715 | |
| -1 | -7,701,715 |
Let's try dividing by 4:
7,701,715 ÷ 4 = 1,925,428.75
If the quotient is a whole number, then 4 and 1,925,428.75 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 | 7,701,715 | |
| -1 | 7,701,715 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 197 | 985 | 1,117 | 1,379 | 5,585 | 6,895 | 7,819 | 39,095 | 220,049 | 1,100,245 | 1,540,343 | 7,701,715 |
| -1 | -5 | -7 | -35 | -197 | -985 | -1,117 | -1,379 | -5,585 | -6,895 | -7,819 | -39,095 | -220,049 | -1,100,245 | -1,540,343 | -7,701,715 |
