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 2,647,715, 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 | 2,647,715 | |
| -1 | -2,647,715 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,647,715.
Example:
1 x 2,647,715 = 2,647,715
and
-1 x -2,647,715 = 2,647,715
Notice both answers equal 2,647,715
With that explanation out of the way, let's continue. Next, we take the number 2,647,715 and divide it by 2:
2,647,715 ÷ 2 = 1,323,857.5
If the quotient is a whole number, then 2 and 1,323,857.5 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 | 2,647,715 | |
| -1 | -2,647,715 |
Now, we try dividing 2,647,715 by 3:
2,647,715 ÷ 3 = 882,571.6667
If the quotient is a whole number, then 3 and 882,571.6667 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 | 2,647,715 | |
| -1 | -2,647,715 |
Let's try dividing by 4:
2,647,715 ÷ 4 = 661,928.75
If the quotient is a whole number, then 4 and 661,928.75 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 | 2,647,715 | |
| -1 | 2,647,715 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 49 | 101 | 107 | 245 | 505 | 535 | 707 | 749 | 3,535 | 3,745 | 4,949 | 5,243 | 10,807 | 24,745 | 26,215 | 54,035 | 75,649 | 378,245 | 529,543 | 2,647,715 |
| -1 | -5 | -7 | -35 | -49 | -101 | -107 | -245 | -505 | -535 | -707 | -749 | -3,535 | -3,745 | -4,949 | -5,243 | -10,807 | -24,745 | -26,215 | -54,035 | -75,649 | -378,245 | -529,543 | -2,647,715 |
