Hi Dayna, Any two positive integers have a common multiple, their product. Thus
is a common multiple of 22 and 25. So is 2 550 = 1100 and 3 550 = 1650, and... So the problem is "Is 550 the smallest common multiple or is their one that is smaller?" As you discovered, there is no smaller number that is a common multiple of 22 and 25 so 550 is the least common multiple of 22 and 25. Penny |
