What is the LCM of 7 8 3 and 4?

To find the Least Common Multiple (LCM) of 7, 8, 3, and 4, you first need to prime factorize each number. The prime factors of the numbers are 7, 2^3, 3, and 2^2. Then, you take the highest power of each prime factor that appears in any of the numbers. So, the LCM of 7, 8, 3, and 4 is 7 * 2^3 * 3 = 168.
