There is really no such thing as a "highest common multiple". Once you find the least common multiple of a set of numbers, you can keep adding the LCM to itself over and over again. Each new number you get will be a common multiple of your set of numbers, but each new number will always be larger than the previous. This means that you can keep adding while the number approaches infinity and you will still never find a greatest multiple.
Least common multiple for 36 and 60 and 135 is 540.
The lowest common multiple is 90 .There is no highest one. If you think you've found the highest one,just add 90 to it, and you'll have a higher common multiple. You cancontinue doing that forever.
HCF(30, 36, 42) = 6 LCM(30, 36, 42) = 1260
GCF requires 2 numbers to compute. "What do you have in common?" begs the question "In common with what?" It is the same thing here.◄
Any multiple of 30 is also a multiple of 15.
Least common multiple of 30 and 135 is 270.
The lowest common multiple of 30, 8 and 135 is 1080
The LCM is: 540
The highest is infinity, because numbers go on for ever. The highest common factor is 6 and lowest common multiple is 60.
I suppose you could say that the highest common multiple is infinity since there are an infinite number of common multiples. If you give a specific number as the highest common multiple, you can always find a larger one.
Least common multiple for 36 and 60 and 135 is 540.
The lowest common multiple is 90 .There is no highest one. If you think you've found the highest one,just add 90 to it, and you'll have a higher common multiple. You cancontinue doing that forever.
The GCF is 10 The LCM is 120
Gcf: 30 lcm: 300
To find the two numbers, we need to consider that their highest common factor is 8 and their lowest common multiple is a multiple of 5. The numbers that satisfy these conditions are multiples of 8 and 5. Therefore, the two numbers are 40 and 80, as they have a highest common factor of 8 and a lowest common multiple of 40.
There is no answer. There cannot be a lowest common multiple of a single number, such as 30, because "common multiple" means a multiple that two or more numbers have in common. Likewise, there cannot be a highest common factor of a single number, such as 3, because "common factor" means a factor that two or more numbers have in common.
The least common factor of 30 and 42 is the smallest number that is a factor of both of them and is 1.However, I suspect that you mean either:What is the highest common factor of 30 and 42?ie what is the highest number that is a factor of both 30 and 42: hcf = 6;What is the lowest common multiple of 30 and 42?ie that is the smallest number that is a multiple of both 30 and 42 lcm = 210.
