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 8,684,495, 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 | 8,684,495 | |
| -1 | -8,684,495 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,684,495.
Example:
1 x 8,684,495 = 8,684,495
and
-1 x -8,684,495 = 8,684,495
Notice both answers equal 8,684,495
With that explanation out of the way, let's continue. Next, we take the number 8,684,495 and divide it by 2:
8,684,495 ÷ 2 = 4,342,247.5
If the quotient is a whole number, then 2 and 4,342,247.5 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 | 8,684,495 | |
| -1 | -8,684,495 |
Now, we try dividing 8,684,495 by 3:
8,684,495 ÷ 3 = 2,894,831.6667
If the quotient is a whole number, then 3 and 2,894,831.6667 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 | 8,684,495 | |
| -1 | -8,684,495 |
Let's try dividing by 4:
8,684,495 ÷ 4 = 2,171,123.75
If the quotient is a whole number, then 4 and 2,171,123.75 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 | 8,684,495 | |
| -1 | 8,684,495 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 43 | 155 | 215 | 1,303 | 1,333 | 6,515 | 6,665 | 40,393 | 56,029 | 201,965 | 280,145 | 1,736,899 | 8,684,495 |
| -1 | -5 | -31 | -43 | -155 | -215 | -1,303 | -1,333 | -6,515 | -6,665 | -40,393 | -56,029 | -201,965 | -280,145 | -1,736,899 | -8,684,495 |
