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.
That's known as the least common multiple, or LCM.
A common multiple
The easiest way is to multiply the numbers together. The answer won't necessarily be the least common multiple, but it will be a common multiple. The easiest way to get a common multiple is to multiply the numbers together. The result will not necessarily be the least common multiple, but it will be a common multiple.
A common multiple is a multiple that two or more given numbers have in common. 16 is not a common multiple of 7 and 8. 16 is a common multiple of 4 and 8. So, it depends on the numbers for which you are trying to find a common multiple.
Lowest Common Multiple-the smallest number that is a multiple of all the numbers in a given set; same as least common multiple. Example-for 6,9, and 18, 18 is the lowest common multiple. =]its lowest common multiple
It is called a common multiple!
"most common multiple" is not a recognised mathematical term. 48 is a common multiple, but it is not the Least Common Multiple (LCM).
There is NO greatest common multiple because I can always add another lowest common multiple and get an ever greater number that is a common multiple.
There is no "most common multiple". To find all common multiples, you start by finding the least common multiple. All other common multiples are multiples of this least common multiple.
Least common multiple of 29 and 30 is 870.
