The highest common multiple is infinite, and not very practical. The GCF is 3. The LCM is 84.
48, because 24 x 2 = 48, 16 x 3 = 48, and 12 x 4 = 48.
The Least Common Multiple of 35 and 3 is 105.
The least multiple is 3. It is not the least COMMON multiple, but the question was not about common multiples.
