For this case, we have that by definition, the LCM of two or more natural numbers, is the smallest natural number that is a common multiple of all of them.
Then the LCM of 15 and 6 is the smallest positive integer that divides the numbers 15 and 6 without leaving a residue.
Multiples of each number:
15: 15,30,45 ...
6: 6,12,18,24,30
So, the LCM is [tex]30w ^ 2[/tex]
Answer:
[tex]30w ^ 2[/tex]
