Co prime numbers have no other common factor except 1 
Eg. 5,7 
     21,32
     11, 13 etc

So if you find the HCF (Highest common factor) And when you can not divide any more with any common facor and you can only divide them with 1 those are called COPRIME NUMBERS with LCM also the same thing happens but a bit different ( LOWEST COMMON MULTIPLE) 
As you just cleared your question your answer is : 11,27
