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 highest multiple.
The Least Common Multiple (LCM) for 7 8 is 56
The least common multiple of 10, 8, and 7 is 280.
The Least Common Multiple (LCM) of 7, 8, and 10 is 280.
The least common multiple of 7 , 8 , 9 = 504
Least Common Multiple (LCM) for 8 7 is 56.
The highest common multiple is infinite. The GCF is 4. The LCM is 8.
It is infinity but the lowest common multiple is 8
The Least Common Multiple of 12, 8, and 7 is 168.
The Least Common Multiple (LCM) for 7 8 is 56
The least common multiple of the numbers 7 and 8 is 56.
The least common multiple of 7 , 3 , 8 = 168
The least common multiple of the numbers 8, 14 and 7 is 56.
The Least Common Multiple (LCM) for 8 7 is 56.
The least common multiple of the numbers 8, 12 and 7 is 168.
The least common multiple of 10, 8, and 7 is 280.
The Least Common Multiple (LCM) of 7, 8, and 10 is 280.
The least common factor of any group of two or more numbers is always 1. The greatest common factor of 3, 5, 7, and 8 is also 1. The least common multiple (LCM) is the multiple of the highest power of prime factors in two or more numbers. Example: LCM of 3, 5, 7, and 8 is 840, which is the multiple of the highest power of all their prime factors, 23 x 3 x 5 x 7.
