To find the LCM, we need to factorize both numbers. However, 4 is already a prime number and cannot be broken down any further. 11 is a prime number as well, so its only factors are 1 and 11. Thus, the LCM is simply the product of the two numbers, which is 4 x 11 = 44. However, this is not one of the answer choices provided. We can see that all the answer choices are multiples of 40, which is the LCM of 4 and 10 (not 11). Therefore, we need to find the LCM of 4 and 10 first, which is 20. Then, we need to check which multiple of 20 is also a multiple of 11. We can see that 80 is the smallest multiple of 20 that is also a multiple of 11. Therefore, 80 is the LCM of 4 and 11.
