To fulfil LCM 2^3 and 3 must be present in (n) and 6. Since 6 is 2x3 , N needs to fulfill criteria of having 2^3 thus N=8

Dont quite understand
Ok dude so this answer works backwards from the LCM 24 which is 2x2x2x3 prime factor right
Then 6 is 2x3
And to get LCM , you normally collect all the prime factors from both numbers but after you look at 2x3 , 2 cube (2^3) is missing so n= 2 cube
Not 12 because only 2x2x3 then missing 2 cubed
Not 24 because your prime factor 3 is already covered by 6
Idk man hope it helps but if you don’t get it google and look at math.com

Hope this helps! Basically you solve it by using the method to deduce the LCM backwards!
