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 8,656,319, 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 | 8,656,319 | |
| -1 | -8,656,319 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,656,319.
Example:
1 x 8,656,319 = 8,656,319
and
-1 x -8,656,319 = 8,656,319
Notice both answers equal 8,656,319
With that explanation out of the way, let's continue. Next, we take the number 8,656,319 and divide it by 2:
8,656,319 ÷ 2 = 4,328,159.5
If the quotient is a whole number, then 2 and 4,328,159.5 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 | 8,656,319 | |
| -1 | -8,656,319 |
Now, we try dividing 8,656,319 by 3:
8,656,319 ÷ 3 = 2,885,439.6667
If the quotient is a whole number, then 3 and 2,885,439.6667 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 | 8,656,319 | |
| -1 | -8,656,319 |
Let's try dividing by 4:
8,656,319 ÷ 4 = 2,164,079.75
If the quotient is a whole number, then 4 and 2,164,079.75 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 | 8,656,319 | |
| -1 | 8,656,319 |
If you did it right, you will end up with this table:
| 1 | 7 | 47 | 83 | 317 | 329 | 581 | 2,219 | 3,901 | 14,899 | 26,311 | 27,307 | 104,293 | 184,177 | 1,236,617 | 8,656,319 |
| -1 | -7 | -47 | -83 | -317 | -329 | -581 | -2,219 | -3,901 | -14,899 | -26,311 | -27,307 | -104,293 | -184,177 | -1,236,617 | -8,656,319 |
