What is the LCM 8 18 and 24?

The least common multiple of 8, 18, and 24 is 72. First look at what 24 can go into: 24, 48, 72, etc. Then check if 18 goes into any of these: 24 (no), 48 (no), but it does go into 72, 4 times (18*4=72). Then check if 8 goes into 72, which it does (8*9=72). Therefore, 72 is the least common multiple.
