What is the least common multiple of 72 and 96?
To find the least common multiple of two numbers, I need to find the smallest positive integer that is a multiple of both numbers. One way to do this is to list the multiples of each number until I find one that is common to both lists. For 72, the multiples are 72, 144, 216, 288, ... For 96, the multiples are 96, 192, 288, ... I see that 288 is the first common multiple in both lists, so it is the least common multiple of 72 and 96.
