No. You can only find the LCM of at least two numbers, prime or otherwise. The LCM of any two prime numbers is their product.

The prime factorization of the LCM will contain all the prime factors of the two original numbers. When the original numbers don't have any prime factors in common, (the GCF is 1) the LCM will be their product. When the two original numbers have prime factors in common (the GCF is 2 or more) the duplicates will be discarded and the LCM will be less than their product.

The LCM of two numbers is sometimes the product of the two numbers.

The product of two prime numbers will be composite.

The LCM of 6 and 13 is 78. Because 13 is prime, the LCM of the two numbers is their product.
