41, yes. 51, no.
The prime factors of 64 are 2, 2, 2, 2, 2, and 2, or 26. The prime factors of 120 are 2, 2, 2, 3 and 5, or 23, 31 and 51. The least common multiple of two numbers is the product of the largest power of each prime encountered in both numbers. In the case of 64 and 120, these are 26, 31, and 51, so the LCM of 64 and 120 is 960.
240 = 24 x 31 x 51
