What is the HCM of 12 and 28?
The highest common multiple (HCM) of 12 and 28 is the least common multiple (LCM) of the two numbers. To find the LCM, first determine the prime factorization of each: 12 is (2^2 \times 3) and 28 is (2^2 \times 7). The LCM takes the highest power of each prime factor: (2^2), (3^1), and (7^1), resulting in (4 \times 3 \times 7 = 84). Therefore, the HCM (or LCM) of 12 and 28 is 84.

Why is 420 the LCM of 1 12 30 84?
Because any smaller positive integer cannot be divided by all the above numbers without remainder. In fact, the presence of 1, when calculating an LCM makes no difference since it will go into any integer. Also, since 12 is a factor of 84, 12 will go into any number that 84 goes into. So the presence of 12 is also irrelevant. Thus, for determining the LCM, only 30 and 84 matter.
What is the least common multiple of 30 and 12?
The Least Common Multiple (LCM) of (12,30) is 60.The lowest common multiple for two numbers can be calculated by:1. Considering the relationship as a ratio.2. Simplifying the ratio (if possible)3. multiplying each original number by the "opposite" ratio.So 12 and 30 are in the ratio of 12 to 30, that is 12:30. This can be simplified to 2:5. You will notice that if we now multiply the 12 by the 5 and the 30 by the 2 we will reach the same answer of 60. 60 is therefore the LCM.
