What is the LCM of 14 and 35 and 42?

Answer 1

One way to find he LCM of two or more numbers is to list the multiples of each until you reach one that the numbers have in common. For example:

14, 28, 42, 56, 70, 84, 98, 112, 126, 140, 154, 168, 182, 196, 210

35, 70, 105, 140, 175, 210

42, 84, 126, 168, 210

210 is the LCM of 14, 35, and 42.
