To find the LCM and gcf of the numbers write them in prime factorisation in power form. Then for the LCM take the highest power of every prime across the numbers, for the gcf take the lower power of every common prime, and multiply them together:
195 = 3 x 5 x 13
390 = 2 x 3 x 5 x 13
LCM = 2 x 3 x 5 x 13 = 390
gcf = 3 x 5 x 13 = 195
but since 195 x 2 = 390LCM is 390
gcf is 195
easy peasy.
