The LCM is: 84
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.
For 7, 5, 4, 3, 2 the LCM is: 420
LCM is 28, which is the multiple of the highest power of prime factors in the given numbers (22 x 7).
the lcm of 1 2 3 4 5 6 7 is 420
LCM of 4 7 12 21 is 84
