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 16,616,603, 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 | 16,616,603 | |
| -1 | -16,616,603 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,616,603.
Example:
1 x 16,616,603 = 16,616,603
and
-1 x -16,616,603 = 16,616,603
Notice both answers equal 16,616,603
With that explanation out of the way, let's continue. Next, we take the number 16,616,603 and divide it by 2:
16,616,603 ÷ 2 = 8,308,301.5
If the quotient is a whole number, then 2 and 8,308,301.5 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 | 16,616,603 | |
| -1 | -16,616,603 |
Now, we try dividing 16,616,603 by 3:
16,616,603 ÷ 3 = 5,538,867.6667
If the quotient is a whole number, then 3 and 5,538,867.6667 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 | 16,616,603 | |
| -1 | -16,616,603 |
Let's try dividing by 4:
16,616,603 ÷ 4 = 4,154,150.75
If the quotient is a whole number, then 4 and 4,154,150.75 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 | 16,616,603 | |
| -1 | 16,616,603 |
If you did it right, you will end up with this table:
| 1 | 23 | 41 | 67 | 263 | 943 | 1,541 | 2,747 | 6,049 | 10,783 | 17,621 | 63,181 | 248,009 | 405,283 | 722,461 | 16,616,603 |
| -1 | -23 | -41 | -67 | -263 | -943 | -1,541 | -2,747 | -6,049 | -10,783 | -17,621 | -63,181 | -248,009 | -405,283 | -722,461 | -16,616,603 |
