Answer 2

Step-by-step explanation:

first write the factors of each number by prime factorisation method

120-2×2×2×5×3

135-5×3×3×3

now pick up common factors in each number

5

now pick up common factors in any two numbers

2,2,2,3

now take the all the remaining factors

2,3,3

now multiply all Commons to get lcm

5×2×2×2×2×3×3×3=2160
