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, and 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.
The highest common multiple of two numbers is their least common multiple (LCM). The LCM of 3 and 5 is found by multiplying the two numbers and dividing by their greatest common divisor (GCD). In this case, the LCM of 3 and 5 is 15, as 3 * 5 / 1 = 15.
15 is a multiple of 3. 15 is a multiple of 5. That makes it a common multiple of 3 and 5.
1 and 3 are the only numbers that have common multiples of 15 and 18.
The highest common multiple of any set of integers is infinite.
The Least Common Multiple of 5, 15, and 3 is 15.
3 and 5 are factors of 15. 15 is a common multiple of 3 and 5.
the answer is 1515 is the lowest common multiple.15 = 3 * 5 and 15 * 1.
15=3*5 27=3*3*3 highest common factor=3
The least common multiple of 3 , 33 , 15 = 165
The least common multiple of 3 , 15 , 35 = 105
The highest common multiple is infinite, and not very practical. The GCF is 3. The LCM is 84.
The Least Common Multiple (LCM) for 5 3 15 is 15.
