The least common multiple of 390 and 661 is 257790, because 257790 is the smallest number that is divisible by both 390 and 661.

Another method to find the least common multiple of 390 and 661 is by using the prime factorization method.
To use prime factorization, we first need to find the prime factors of 390 and 661, and then get the LCM by multiplying the prime factors that are rasied to their highest power from the two sets.

Prime factorization of 390 = 2 x 3 x 5 x 13
Prime factorization of 661 = 661
Prime factors to the highest power = 13 x 2 x 3 x 5 x 661 = 257790
