One way to do this is "prime factorization": \(\displaystyle 84 = 2^2 \cdot 3 \cdot 7\) \(\displaystyle 135 = 3^3 \cdot 5\) \(\displaystyle 60 = 2^2 \cdot 3 \cdot 5\) \(\displaystyle 160 = 2^5 \cdot 5\) So the least common multiple is (product of all the prime factors with highest exponent) \(\displaystyle LCM = 2^5 \cdot 3^3 \cdot 5 \cdot 7\)
