The numbers 1080, 1188 and 1815, written as the products of their prime factors, are 1080 = 23 x 33 x 5, 1188 = 22 x 33 x 11 and 1815 = 3 x 5 x 112. Hence, find the greatest whole number that will divide 1080, 1188 and 1815 exactly.

In all honesty, there really is no “work” per say to show. mainly it’s just using the process of elimination. the question is asking which domain(s) would be the most appropriate for the function c(n). n is the number of observed vehicles so right away, 1, 2, and 3 can be eliminated.why? 1, 2 start in the negatives and therefore it is impossible to observe negative cars. so, #4 would be the best answer to the given problem.
