If m and n are positive integer, and 1800m=n^3, what is the least possible value of m?	Choose the correct choice from the following choices:
A) 2	B) 3	C) 15	D) 30	E) 45
1800*m=n^3   m=n^3/1800   =n^3/(3^2*5^2*2^3)   so n has to be 3*5*2 so that n^3 is divisible by 1800.   So m= (2*3*5)^3/(3^2*5^2*2^3)   m=15   ANSWER:15
