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 6,865,615, 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 | 6,865,615 | |
| -1 | -6,865,615 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 6,865,615.
Example:
1 x 6,865,615 = 6,865,615
and
-1 x -6,865,615 = 6,865,615
Notice both answers equal 6,865,615
With that explanation out of the way, let's continue. Next, we take the number 6,865,615 and divide it by 2:
6,865,615 ÷ 2 = 3,432,807.5
If the quotient is a whole number, then 2 and 3,432,807.5 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 | 6,865,615 | |
| -1 | -6,865,615 |
Now, we try dividing 6,865,615 by 3:
6,865,615 ÷ 3 = 2,288,538.3333
If the quotient is a whole number, then 3 and 2,288,538.3333 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 | 6,865,615 | |
| -1 | -6,865,615 |
Let's try dividing by 4:
6,865,615 ÷ 4 = 1,716,403.75
If the quotient is a whole number, then 4 and 1,716,403.75 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 | 6,865,615 | |
| -1 | 6,865,615 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 115 | 227 | 263 | 1,135 | 1,315 | 5,221 | 6,049 | 26,105 | 30,245 | 59,701 | 298,505 | 1,373,123 | 6,865,615 |
| -1 | -5 | -23 | -115 | -227 | -263 | -1,135 | -1,315 | -5,221 | -6,049 | -26,105 | -30,245 | -59,701 | -298,505 | -1,373,123 | -6,865,615 |
