The given numbers in their hexadecimal form are:
- 11ebbb8f_b96f_0438_bcf2_37e018a8e4d8 = a * b * c * d * e, where a = 11ebbb8f_b96f_0000_0000_0000_0000_0000_0000, b = 0000_0000_0000_0000_0000_0000_0000_0011, c = 0000_0000_0000_0000_0000_0000_0000_0111, d = 37e018a8e4d8_0000_0000_0000_0000_0000_0000_0000, e = 0000_0000_0000_0000_0000_0000_0000_0011
- TB8306_11 = r(r + 7), where r = TB8306_10 in decimal form

To find the LCM, we need to find the highest power of each prime factor that occurs in the factorization of the given numbers. Since a and d have no common prime factors with r(r + 7), the LCM can be obtained by multiplying all the given numbers: 
LCM = a * b * c * d * e * r(r + 7) = 11ebbb8f_b96f_2b4a_bcf2_9168c01e1781_TB8306_11
