You need at least two numbers to find an LCM.
The least multiple is 3. It is not the least COMMON multiple, but the question was not about common multiples.
The Least Common Multiple of 3 and 20 is 60.
The least common multiple of 3 , 13 = 39
The least common multiple of 3 , 23 = 69
The least common multiple of 3 , 180 = 180
The least common multiple of 10117 , 3 is 30,351
The least common multiple of 3 , 35 = 105
The least common multiple of 8 , 3 = 24
The least common multiple of 3 , 47 = 141
The Least Common Multiple of 35 and 3 is 105.
The least common multiple of 3 and 14 is 42.
the least common multiple for 3 and15 is 30
