33 = 3 x 11
39 = 3 x 13
Note that there are 3 columns ( 3, 11, 13) and they are all prime numbers (prime factorisation)
To find the LCM, multiply the highest number in each column, so, 3 x 11 x 13 = 429
So, the LCM is 429

The least common multiple (LCM) is: 39
Least Common Multiple (LCM) for 39 23 is 897.
The greatest common factor of 33, 27 & 39 is 3.
24. A multiple of (x), for example, is a number divisible by x. So multiples of 3 are 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36, 39, 42, 45, 48 ...etc. Multiples of 8 are 8, 16, 24, 32, 40, 48 ...etc. Since the lowest multiple which 3 and 8 have in common is "24", it is called the "LCM" (a.k.a. Lowest Common Multiple). 48 is a common multiple shared by 3 and 8, but it is not the lowest. This is essentially a mathematical / analytical proof, so I hope it helps.
Least common multiple of 26 and 39 and 52 is 156.
