Question 576745: Let p, q, and r be three different odd prime numbers. What are LCM (2pq, 2pr, 2qr) and GCF (2pq, 2pr, 2qr)? Justify your answers.

pq, pr, and qr are all relatively prime (LCM of the three is pqr). The LCM of 2pq, 2pr, and 2qr would therefore be 2pqr.

The GCF of 2pq, 2pr, 2qr would be 2 because no other factor divides all three of them.
