To find the LCM, you can use the prime factorization method or list the multiples of each number. Prime factorization involves breaking down numbers into their prime factors and constructing the smallest number with all the factors. Listing multiples involves finding the smallest shared multiple. Both methods help find the LCM of numbers like 18 and 12.

Step by step, you’ll see how we divide the given numbers simultaneously by prime numbers, continuing the process until no common factor remains except 1. By multiplying all the divisors and the remaining numbers together, we arrive at the LCM in a simple and systematic way.
