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 8,064,715, 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 | 8,064,715 | |
| -1 | -8,064,715 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,064,715.
Example:
1 x 8,064,715 = 8,064,715
and
-1 x -8,064,715 = 8,064,715
Notice both answers equal 8,064,715
With that explanation out of the way, let's continue. Next, we take the number 8,064,715 and divide it by 2:
8,064,715 ÷ 2 = 4,032,357.5
If the quotient is a whole number, then 2 and 4,032,357.5 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 | 8,064,715 | |
| -1 | -8,064,715 |
Now, we try dividing 8,064,715 by 3:
8,064,715 ÷ 3 = 2,688,238.3333
If the quotient is a whole number, then 3 and 2,688,238.3333 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 | 8,064,715 | |
| -1 | -8,064,715 |
Let's try dividing by 4:
8,064,715 ÷ 4 = 2,016,178.75
If the quotient is a whole number, then 4 and 2,016,178.75 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 | 8,064,715 | |
| -1 | 8,064,715 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 79 | 85 | 395 | 1,201 | 1,343 | 6,005 | 6,715 | 20,417 | 94,879 | 102,085 | 474,395 | 1,612,943 | 8,064,715 |
| -1 | -5 | -17 | -79 | -85 | -395 | -1,201 | -1,343 | -6,005 | -6,715 | -20,417 | -94,879 | -102,085 | -474,395 | -1,612,943 | -8,064,715 |
