To find the least common multiple (LCM) of two or more numbers, you can follow these steps:

1. Identify the numbers for which you want to find the LCM.

2. Determine the prime factors of each number.

3. Multiply the highest power of each prime factor together to get the LCM.

For example, let's find the LCM of 12 and 18:

Prime factorization of 12: 2^2 * 3

Prime factorization of 18: 2 * 3^2

To find the LCM, take the highest power of each prime factor:

2^2 * 3^2 = 4 * 9 = 36

So, the LCM of 12 and 18 is 36.
