If the least common multiple of two numbers, 1728 and K is 5184,
Please scroll down to see the correct answer and solution guide.
Right Answer is: D
The uncommon factor of K and 1728 = 5184/1728 = 3
Let K = 2a x 3b
Now, because we take maximum powers of the prime factors in the L.C.M
Hence K is a multiple of and power to 2 is less than 6.
Total possible values of m are
Hence number of possible values of K are 7.
