To find the Least Common Multiple (LCM) of 4, 3, 7, and 5, we first need to prime factorize each number. The prime factors of 4 are 2^2, 3 is a prime number itself, 7 is a prime number, and 5 is also a prime number. The LCM is then calculated by taking the highest power of each prime factor that appears in any of the numbers, which results in 2^2 * 3 * 5 * 7 = 420. Therefore, the LCM of 4, 3, 7, and 5 is 420.
