=20 Yes, guaranteed! -----Original Message----- From: piclist-bounces@mit.edu [mailto:piclist-bounces@mit.edu] On Behalf Of Marcel Duchamp Sent: Friday, September 27, 2013 7:51 PM To: Microcontroller discussion list - Public. Subject: [OT] Prime factors This is just idle curiosity but since there are people on this list - most of them - smarter than me, someone probably knows the answer. If a and b are prime numbers, and their product a X b is c, then is c divisible by *only* a and b? Guaranteed? My feeling is that it is but I lack the knowledge of what to search for to find the definitive answer. BTW, this does *not* involve, for me, any sort of cryptography. In other words, I'm not trying to re-invent any crypto ciphers.
