hcf(14, 30) = 2
lcm(14, 30) = 210
14 = 2 x 7
30 = 2 x 3 x 5
hcf = 2
lcm = 2 x 3 x 5 x 7 = 210

Use GCF instead of HCF. 6 and 30 would be those numbers...
HCF = 3... LCM = 18 !
The HCF is always a factor of the LCM of two numbers. The HCF is a factor of both the numbers which are factors of their LCM. Thus the HCF is also a factor of the LCM of the two numbers.
The LCM (least common multiple) of numbers a,b is defind as (a*b)/(hcf(a,b)) the hcf(16,14) can be found with Euclid algorithm 16=(14)(1)+2 14=(2)(7)+0 thus hcf(16,14)=2 16*14=224 224/2=112 thus the LCM of 14 and 16 is 112
5 and 10 lcm- 10 and hcf= 5
