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; orLowest Common Multiple - the lowest number which is a multiple of both 21 and 28 which is 84.
The highest common multiple of any set of integers is infinite.
The highest common multiple of any set of integers is infinite.
There is no limit to the size of the highest common multiple. Highest common factor is 2 and lowest common multiple is 176.
The least common multiple of 7 and 28 is 28.
LCM is 28, which is the multiple of the highest power of prime factors in the given numbers (22 x 7).

LCM is 420, which is the multiple of the highest power of prime factors in the given numbers (22 x 3 x 5 x 7).
There is no such thing as a Highest Common Multiple (HCM), for it always equals to infinity, since multiples always stretch forever.For example, the HCM of 4 and 7.Multiples of 4: 4, 8, 12, 16, 20, 24, 28, ... infinityMultiples of 7: 7, 14, 21, 28, 35, 42, 49, ...infinityAccording to the working, the highest common factor of any number will always be infinity.Very little in a practical sense. The highest common multiple of any set of numbers is an infinite amount.The highest common multiple is an infinite number and has very little practical use.
Highest common multiple of 24 and 18 is 6.
LCM is 28, which is the multiple of the highest power of prime factors in the given numbers (22 x 7).
This cannot be answered because the common multiples of any two or more numbers are infinite.
The highest common multiple of any set of integers is infinite.
The third multiple of 28 is 84.
28 is a factor of 28, as 28/28 = 1. 28 is also a multiple of 28, as 28*1 = 28.
28 ÷ 8 = 3.5. Therefore, 28 is not a multiple of 8.
There is no highest common multiple. Whatever common multiple you come up with as being their highest common multiple, I can always add their lowest common multiple (120) to get a higher common multiple.
