48

60

72

80​

Answer 1

Answer:

80

Step-by-step explanation:

LCM of any two numbers is always divisible by their HCF

here, 80 is not divisible by 6...therefore, that's the answer

Answer 2

H.C.F stands for Highest Common Factor it is the greatest number that divides each of the two or more numbers whereas LCM stands for Least Common Multiple, the LCM of any two numbers is the value that is evenly divisible by the two given numbers.

$48\div6=8\\60 \div6=10\\ 72\div6=12\\ 80\div 6=13.33$

Here we can see that 80 is not completely divisible by 6, thus 80 can never be the LCM.
