Quizplus · Accepted Answer

The only common factor between 3 and 11 is 1. 
Multiplying the two numbers we get, 3 * 11 = 33. 
The factors of 33 are 1, 3, 11, and 33. 
The LCM of 3 and 11 will be the smallest number which is divisible by both the numbers, and thus will be 33 in this case. 
Also, 33 is divisible by 3, so one of the choices is 3. However, it is not the LCM of 3 and 11. 
Thus, the best choice is option D) 45, which is divisible by 3 and is also the LCM of the given numbers 3 and 11.
