Answer:

D) 2² × 3² × 5 × 7  

Step-by-step explanation:

Data:  

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
