Answer:

$\huge\mathfrak\pink{☆Answer☆}$

Step-by-step explanation:

Numbers=>18 and 60

=>18 =2*3*3

=2*3^2.

=>60=2*2*3*5

=>2^2*3*5.

As LCM is the product of the highest power of each factor.

So LCM(18,60)=2*2*3*3*5

=2^2*3^2*5

=4*9*5

=36*5

=180.

So the LCM of 18 and 60 is 180 which is the required answer.
