The LCM is 1848.
The Least Common Multiple (LCM) for 66 10 42 is 2,310.
The Least Common Multiple (LCM) for 21 42 66 1500 is 115,500
462
462
Unless there is a common factor, LCM is the product. 42 = 2 x 3 x 7; 66 = 2 x 3 x 11. There are common factors of 2 and 3 so one occurrence is to be ignored when multiplying ie 2 x 3 x 7 x 11 so LCM = 462 (11 x 42, 7 x 66)
