Answer:

72r^3t^4

Explanation:
* and x = times tables btw

First you'll want to rewrite the equation:
12r^3
18r^2t
24t^4

Then factor the monomial, 12r^3=2*2*3*r*r*r
18r^2t
24t^4

Finding the lease common multiple of the expressions, write the product of all factors the greatest number of times they appear in factorization.

12r^3=2*2*3*r*r*r
18r^2t=2*3*3*r*r*t
24t^4=2*2*2*3*t*t*t*t
Your answer is
2 x 2 x 2 x 3 x 3 x r x r x r x t x t x t
simplify it and you get
72r^3t^4
