    D) 2² * 3² * 5 * 7

    Step-by-step explanation:

    dа ta:

    Factors of first number = 2² * 3 * 5

    Factors of second number = 2 * 3² * 2 * 7

    Calculations:

    Rewrite the factors in ascending order

    Factors of first number = 2² * 3 * 5

    Factors of second number = 2² * 3² * 7

    Multiply each factor by the greatest number of times it occurs in either number

    LCM = 2² * 3² * 5 * 7
