What is the least common multiple of 21 77 and 63?

The LCM of a group of numbers is the smallest number that all of the given numbers will divide into.The LCM will always be the largest of the given numbers or its multiple. In our case, the largest number is 77. Since 21 and 63 will not divide into 77, the LCM will be a multiple of 77. That multiple will be the number 693 (77 x 9), because: 693/21 = 33 or 21 x 33 = 693; 693/63 = 11 or 63 x 11 = 693. Thus the LCM is 693.
