Apart from the first, all the other powers are missing!
Since 2^6 x 3^3 x 5 is a multiple of 2^3 x 3^3 x 5, it is automatically the LCM.
The LCM is 300.
Since 4 is a multiple of 2, it is automatically the LCM.
It is: 12
It is: 24
The LCM is 6b2c3
Note that 16X is a factor of 32X [16X times 2 is 32X]. So now whether it's (32X)^4 or 32 times (X^4), that will still be the LCM, so the answer is 32X to the 4th power, just as it's stated in the question.

the LCM of 42 and 126 using a prime factorization is 2 times 2 times 3
The question is somewhat ambiguous: the answers are LCM[3T2, 5T] =15T2 or LCM[(3T)2, 5T] =45T2
3x5x6 = 90LCM of 18 and 30 = 90 Prime factorization of:18 = 2 * 3 * 330 = 2 * 3 .....* 5===========LCM=2 *3 * 3 * 5 = 90
