The least common multiple (LCM) can be determined by factoring out the terms first,
                             165xy = (3)(11)(5)(x)(y)
                              77x³y = (7)(11)(x)(x)(x)(y)
Copy the factors writing off the repeated factors only once,
                        LCM = (3)(11)(5)(x)(y)(7)(x)(x)= 1155x³y
The answer is 1155x³y (first choice) 

Answer:

[tex]1,155x^3y[/tex]

Step-by-step explanation:

Find LCM of [tex]165xy \ and \ 77x^3y[/tex]

We write the expression in factors

[tex]165xy= 3 \cdot 11 \cdot 5 \cdot x \cdot y[/tex]

[tex]77x^3y= 11 \cdot 7 \cdot x \cdot x \cdot x \cdot y[/tex]

To find LCM, w multiply  all the common factors first 11xy

Now we multiply all the remaining terms

[tex]LCM = 11xy \cdot 3 \cdot 5 \cdot x \cdot x \cdot 7= 1155x^3y[/tex]
