LCM= 68,14,80,800
Step-by-step explanation: We have to only write the number in the multiple of their prime factors
25= 5 x 5
37= 1 x 37
52= 2 x 2 x 13
7=1x7
=> 25 x 37 x 52 x 7= 2 x 2 x 5x5x7x
13 x 37
23= 1 x 23
32= 2 x 2 x 2 x 2 x 2
56= 2 x 2 x 2 x 7
=> 23 x 32 x 56 x 11= 2 x 2 x 2 x 2 x 2 x 7 x 11 x 23
HCF = 2 x 2 x 7= 28
LCM= 2 x 2 x 2 x 2 x 2 x 5 x 5 x 7 x 11 x 13 x 23 x 37 = 68,14,80,800
