Answer:
see below
Explanation:
13. LCM of 24 , 30, 36:-
24 = 2*2*2*3
30 = 2*3*5
36 = 2*2*3*3
There 3 2's common to all 3 factors. Also 3 3's. So these 2 numbers only appear once in process. Also There are 2 2's in the factors of 24 and 36 so this only appears once also.
LCM = 2*3*2*2*3*5
= 360
15.
24 32 16
24 = 2*2*2*3
32= 2*2*2*2*2
16 = 2*2*2*2
LCM = 2*2*2*2*2*3
= 96
17
8 = 2*2*2
22= 2*11
6 = 2*3
LCM = 2*2*2*3*11
= 264
