1) 306 = 2*2*7*11 = 2*3²*17
657 =  3*3*73 = 3²*73
Lcm = product of all prime factors with highest power = 2*3²*17* 3²*73 = 201042
Hcf = product of prime factors with lowest power = 3
² = 9

2) 17 = 1*17
23 = 1*23
29 = 1*29
Lcm = 
1*17*1*23*1*29 = 11339
Hcf = 1

3) 8 = 2³
9 = 3²
25 = 5²
Lcm = 2³*3²*5² = 1800
Hcf = 1
2 5 2
