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 8,300,663, 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 | 8,300,663 | |
| -1 | -8,300,663 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,300,663.
Example:
1 x 8,300,663 = 8,300,663
and
-1 x -8,300,663 = 8,300,663
Notice both answers equal 8,300,663
With that explanation out of the way, let's continue. Next, we take the number 8,300,663 and divide it by 2:
8,300,663 ÷ 2 = 4,150,331.5
If the quotient is a whole number, then 2 and 4,150,331.5 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 | 8,300,663 | |
| -1 | -8,300,663 |
Now, we try dividing 8,300,663 by 3:
8,300,663 ÷ 3 = 2,766,887.6667
If the quotient is a whole number, then 3 and 2,766,887.6667 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 | 8,300,663 | |
| -1 | -8,300,663 |
Let's try dividing by 4:
8,300,663 ÷ 4 = 2,075,165.75
If the quotient is a whole number, then 4 and 2,075,165.75 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 | 8,300,663 | |
| -1 | 8,300,663 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 133 | 139 | 449 | 973 | 2,641 | 3,143 | 8,531 | 18,487 | 59,717 | 62,411 | 436,877 | 1,185,809 | 8,300,663 |
| -1 | -7 | -19 | -133 | -139 | -449 | -973 | -2,641 | -3,143 | -8,531 | -18,487 | -59,717 | -62,411 | -436,877 | -1,185,809 | -8,300,663 |
