What is the least common multiple of 15, 16, and 24?
Select:
A) 60  B) 120  C) 240  D) 360  E) 720
Let us first write the numbers in the form of prime factors:   15 = 3*5   16 = 2^4   24 = 2 * 17^1   The LCM would be the largest powers of the prime numbers from all these three numbers.   Hence L240M = 240   Option 240
