The multiples of 4 are 4, 8, 12, 16, 20, 24
The multiples of 6 are 6, 12, 18, 24
This means that the LCM of 4 and 6 is actually 12 and not 24 because 12 is the lowest shared multiple of these two numbers (4 and 6).

The least common multiple of two numbers is the product of the two numbers divided by their greatest common factor. The greatest common factor of 4 and 8 is 8. (See related question "What is the greatest common factor of 4 and 8?" for this calculation.) So, the least common multiple is 4 x 8 ÷ 4 = 8. Common multiples of 4 and 8 include 8, 16, 24, 32, 40, 48, 56, 64, 72, 80, etc. Although 16 is a common multiple, it is not the least common multiple.
least common multiple will be 88 itself
There are infinitely many common multiples of 24 and 4. Those are all numbers of form t = 24n, where n = 1, 2, 3, ..., because 24 itself is divisible by 4. The least common multiple of 4 and 24 is 24.
The least common multiple of 4 , 5 , 3 , 7 = 420
The Least Common Multiple (LCM) for 4 6 is 12.
