    Answer:

    Alternatively, the lcm of 21 and 42 can be found using the prime factorization of 21 and 42: The prime factorization of 21 is: 3 x 7. The prime factorization of 42 is: 2 x 3 x 7. Eliminate the duplicate factors of the two lists, then multiply them once with the remaining factors of the lists to get lcm(21,21) = 42.
