The common multiples of 21 and 28 are 84, 168, 252, 336, ... and so on, never ending; so there is no real Highest Common Multiple.
Do you mean:
- Highest Common Factor - the highest number which divides both 21 and 28 which is 7; or
- Lowest Common Multiple - the lowest number which is a multiple of both 21 and 28 which is 84.

What is the hcm of 14 and21?
The highest common multiple (HCM) of two numbers is not a standard mathematical term; you might be referring to the least common multiple (LCM). The LCM of 14 and 21 is found by determining the smallest multiple that both numbers share. The LCM of 14 (2 × 7) and 21 (3 × 7) is 42, as it is the smallest number that both can divide evenly.
What is the answer to this question two numbers have a lcm of 24 and a hcm of 2 what is the answer?
This question as written has no rational answer since the value of an hcm, being infinite, is unquantifiable. If you change the hcm to GCF, you could use 6 and 8 or 24 and 2.
