Happy Birthday, Bryan

Happy 30th, cupcake!

Trust me when I say life only gets better from here.

Did you know that 30 is the smallest sphenic number?

And the smallest of the form $2\cdot 3\cdot r$ where r is a prime greater than 3. 30 has an aliquot sum of 42 and all sphenic numbers of this form have an aliquot sum 12 greater than themselves?

You probably did.
