The number of positive integer pairs (m, n) where n is odd, that satisfy `1/m+4/n=1/12` is

Find the number of pairs of positive integers (m,n) with m le n , such that the 'least common multiple' (LCM) of m and n equals 600.

How many pairs of positive integers m and n satisfy the equation (1)/(m) +(4)/(n) =(1)/(12) where n is an odd integer less than 60?
