Answer: The LCM of 18 and 6 is 18.
Step-by-step explanation: To find LCM:
Step 1: Find the prime factorization of 18 and 6.
The prime factorization for 6 in exponential form is 2 and 3. (2x3=6)
The prime factorization for 18 in exponential form is 2, 3^2. (2x3x3=18)
Multiply the highest exponent prime factors to find the LCM.
LCM (18,6) = 2^1 x 3^2
LCM = 18
