Prove that Dexter is wrong

To prove that Dexter is wrong, we use the following numbers.

Number = 4

The factors are:

Factor = 1,2\ and\ 4

3 factors

Using a greater number:

Number = 5

The factors are:

Factor = 1\ and\ 5

2 factors

From the above analysis:

4 has 3 factors and 5 has 2 factors; which shows that 5 has fewer factors

This shows that Dexter is wrong
