    Again reduce each term to prime factors: 15x is 3*5*x and 45y is 3*3*5*y so the LCD becomes 3*3*5*x*y LCD is 45xy

    The LCD has the prime factors that are present in its product, when individual products have multiple prime factors you should use the maximum times it occurs in a tern, In the above 45 had 3 as a factor twice, therefore two 3s were used to obtain the LCD
