  1. Answer:

    Answer = 84

    Step-by-step explanation:

    Find the prime factorization of 28. 28 = 2 × 2 × 7.

    Find the prime factorization of 42. 42 = 2 × 3 × 7.

    Multiply each factor the greater number of times it occurs in steps i) or ii) above to find the LCM: LCM = 2 × 2 × 3 × 7.

    LCM = 84.
