What is the LCM of 57 24 33 15?

Answer 1

If there are no common factors the LCM is the product of all four numbers. 15 = 3 x 5, 24 = 2 x 2 x 2 x 3, 33 = 3 x 11, 57 = 3 x 19. The only common factor is 3 so one occurence of it can be ignored when multiplying out: 5 x 24 x 33 x 57 = 225720. ie LCM is 225720
