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 16,000,663, 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 | 16,000,663 | |
| -1 | -16,000,663 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,000,663.
Example:
1 x 16,000,663 = 16,000,663
and
-1 x -16,000,663 = 16,000,663
Notice both answers equal 16,000,663
With that explanation out of the way, let's continue. Next, we take the number 16,000,663 and divide it by 2:
16,000,663 ÷ 2 = 8,000,331.5
If the quotient is a whole number, then 2 and 8,000,331.5 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 | 16,000,663 | |
| -1 | -16,000,663 |
Now, we try dividing 16,000,663 by 3:
16,000,663 ÷ 3 = 5,333,554.3333
If the quotient is a whole number, then 3 and 5,333,554.3333 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 | 16,000,663 | |
| -1 | -16,000,663 |
Let's try dividing by 4:
16,000,663 ÷ 4 = 4,000,165.75
If the quotient is a whole number, then 4 and 4,000,165.75 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 | 16,000,663 | |
| -1 | 16,000,663 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 29 | 149 | 161 | 203 | 529 | 667 | 1,043 | 3,427 | 3,703 | 4,321 | 4,669 | 15,341 | 23,989 | 30,247 | 78,821 | 99,383 | 107,387 | 551,747 | 695,681 | 2,285,809 | 16,000,663 |
| -1 | -7 | -23 | -29 | -149 | -161 | -203 | -529 | -667 | -1,043 | -3,427 | -3,703 | -4,321 | -4,669 | -15,341 | -23,989 | -30,247 | -78,821 | -99,383 | -107,387 | -551,747 | -695,681 | -2,285,809 | -16,000,663 |
