Thanks for writing Dr. Math!

Actually there are an infinite number of numbers with only two prime
factors and no repeated factors.  To find one, think of two prime
numbers.  Now multiply them together once (so there are no repeated
factors).  Your result is a number with only two prime factors and
no repeated factors. :-)

Example:

Pick two prime numbers.  How about 2 and 3?

Now, multiply them together once.

2*3 = 6

Therefore, 6 has only two prime factors and no repeated factors.

If you have any questions or if this was a little confusing, please
let me know!
