Answer:
From the above three equations, we can see that the common factors of 6, 72, and 120 is 2×3=6. So, we get the highest common factor or HCF of 6, 72, and 120 as 6. Hence, the LCM of the three numbers is 360.

Answer:
no, because three are three numbers...
when there are two numbers,this formula is applicable.
Step-by-step explanation:
LCM for them is 360
HCF of them is 6
L C M x H C F = 360x6
= 2160
product of numbers = 6x72x120 = 51,840
therefore, the LCMxHCF ≠ product of 3 numbers
