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.

What is the LCM of 130 and 195?
To find the Least Common Multiple (LCM) of 130 and 195, you first need to find the prime factorization of each number. The prime factorization of 130 is 2 x 5 x 13, and the prime factorization of 195 is 3 x 5 x 13. Then, you identify the common prime factors and their highest powers, which are 2, 3, 5, and 13. Finally, you multiply these common prime factors with their highest powers to find the LCM, which is 2 x 3 x 5 x 13 = 390.
What is the GCF of 130 and 390?
Since 130 is a factor of 390, it is automatically the GCF.
