The Least Common Multiple (LCM) for 21 42 66 1500 is 115,500
462
462
The least common multiple of 10 and 66 is 330.
The LCM of 10 and 42 is 210
210
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)
LCM of 15 and 66 is 330.
The LCM is 66.
Because 210 is the smallest number that both 30 and 42 divide into equally with no remainder.
