Photo from Steve's site (https://www.alpsroads.net/roads/oh/city_53/), two nutty City Routes in Fremont, Ohio.  53 × 6 = 318

That and many other great specimens on that page plus https://www.alpsroads.net/roads/oh/city_12/ .

Here's a similar situation along I-270 in Ohio, that isn't GSV.

323 = 17 x 19 near Detroit, Alabama:

[paulthemapguy]

YES! Someone knew that 323 wasn't a prime number, AND found an instance of the two factors together!

And now for a MUCH more composite number:

324 = 12 × 27

US 11 * New York 30 = 330 in Malone.  June 27, 2011.

[paulthemapguy]

I was HOPING someone would discover that 329 isn't a prime number, and would also discover a photo that works.

I had a 330 ready to go, but Jim beat me to the punch! His photo probably looks nicer than mine would have, anyway.

331 is indeed prime, so...  331 = 331 × 1 on US20 in Indiana
