The highest common multiple of any set of integers is infinite.


What is the highest common multiple of 12and 21?

The highest common multiple is infinite, and not very practical. The GCF is 3. The LCM is 84.


What is the highest multiple of 14 and 21?

The highest multiple of both 14 and 21 is their least common multiple (LCM). To find the LCM, we first determine the prime factorization of both numbers: 14 is (2 \times 7) and 21 is (3 \times 7). The LCM is calculated as (2^1 \times 3^1 \times 7^1 = 42). Therefore, the highest multiple of 14 and 21 is 42.
